genera un algoritmo que identifique si el numero es un palindromo o no

int palindromo(int num)
{
    int rev = 0, r;
    while (num > 0) {
        r = num % 10;
        num = num / 10;
        rev = rev * 10 + r;
    }
    return rev;
}

int main(int argc, char *argv[])
{
    int num, rev;
    printf("Enter a number: ");
    scanf("%d", &num);
    rev = palindromo(num);
    if (num == rev)
        printf("%d is a palindrome\n", num);
    else
        printf("%d is not a palindrome\n", num);
    return 0;
}
