Thread: print alternate characters in string

i want to write program to print alternate characters in string
i have tried following code but it prints first character at infinte times
whats wrong in below code?

Code:

#include <stdio.h>


int main()
{
  char s[100];int i,l;
  printf("Enter string ");
  scanf("%s",s);
  for(i=0;i<=strlen(s);i+2)
    printf("%c",s[i]);
}

Code:

scanf("%s",s);

If I enter:

Code:

This is a test.

s will only contain, "This". You should use fgets() to input the entire string. Please remember that fgets() will also bring in the '\n' newline character at the end of the string entered.

thx for reply
