*/

#include <stdio.h>

int main()

{

            int n, reversedN = 0, remainder, originalN;

            printf("Enter an integer: ");

            scanf("%d", &n);

            originalN = n;

            // reversed integer is stored in reversedN

            while (n != 0)

{

                        remainder = n % 10;

                        reversedN = reversedN * 10 + remainder;

                        n /= 10;

            }

            // palindrome if orignalN and reversedN are equal

            if (originalN == reversedN)

            {

                        printf("%d is a palindrome.", originalN);

            }

            else

            {  

                        printf("%d is not a palindrome.", originalN);

            }

return (0);

}

OUTPUT :

Enter an integer: 1001

1001 is a palindrome.
