C program to check whether a string is palindrome or not using while loop.




C program to check whether a string is palindrome or not using while loop.



#include <stdio.h>

#define MAX 100
int main()
{
    char text[MAX];
    int len, start, end;

    printf("Enter any string: ");
    gets(text);


    /* Find length of the string */
    len = 0;
    while(text[len] != '\0') len++;

    start = 0;
    end   = len-1;


    while(start <= end)
    {
        if(text[start] != text[end])
            break;

        start++;
        end--;
    }

    if(start >= end)
    {
        printf("String is Palindrome.");
    }
    else
    {
        printf("String is Not Palindrome.");
    }

    return 0;
}


Output:

Enter any string: rama

String is Not Palindrome.

Enter any string: madam
