C PROGRAM FOR STRING PALINDROME

   

Consider the following I/O samples.

SAMPLE INPUT: radar

SAMPLE OUTPUT: Palindrome

The algorithm used here is :

1. Input string.
2. Reverse the string.
3. Check the reversed string and the original string.
4. If the strings are same, it is a Palindrome.
5. Print the output.

C PROGRAM:  

#include <stdio.h>

#include <string.h>

int main()

{

    char string1[20];

    int i, length;

    int flag = 0;

    printf("Enter a string:");

        scanf("%s", string1);

    length = strlen(string1);

    for(i=0;i < length ;i++)

    {

        if(string1[i] != string1[length-i-1])

        {

            flag = 1;

            break;

       }

    }

    if (flag) 

        printf("%s is not a palindrome", string1);

    else 

        printf("%s is a palindrome", string1);

    return 0;

}

OUTPUT:

The given source code in C program "for String Palindrome" is short and simple to understand. The source code is well tested in DEV-C++ and is completely error free.
