int main (void)

{

     char str[20];

     char revstr[20];

     //Input string

     printf ("Input String: ");

     gets (str);

     //Copy and Reverse string

     strcpy (revstr, str);

     strrev (revstr);

     //Check if the string is palindrome or not and print result

     if (strcmp (str, revstr))

          printf ("%s is not palindrome.", str);

     else

          printf ("%s is palindrome.", str);

     return 0;

Output

Input String: NITIN

NITIN is palindrome.
