6) Write a program to checks given String is Palindrome or not.

 source file name: palindr.C

#include <string.h>

#include<stdio.h>

int  main()

{

    char str[20];

    int i, len;

    int op = 0;

   //clrscr();

    printf("Enter a string:");

    scanf("%s", str);

    len = strlen(str);

    for(i=0;i < len ;i++)

    {

if(str[i] != str[len-i-1])

{

    op = 1;

    break;

}

    }

    if (op)

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

    else

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

    //getch();

return 0;

}

output:
