Check whether a number is a palindrome or not with C

#include <stdio.h>

int main()
{
    int n, num, reverse = 0;
    printf("Enter any number to check palindrome: ");
    scanf("%d", &n);

    num = n;
    while (n != 0)
    {
        reverse = (reverse * 10) + (n % 10);
        n /= 10;
    }

    if (reverse == num)
    {
        printf("%d is palindrome.", num);
    }
    else
    {
        printf("%d is not palindrome.", num);
    }

    return 0;
}

Output:-

Enter any number to check palindrome : 1221
1221 is palindrome.
