Program to check a number is Palindrome or not

#include<stdio.h>
int palindrome(int num){
int num1 = num,id,rev;
while(num>0){
id = num%10;
rev = rev*10+id;
num = num/10;
}
if(rev==num1){
printf("palindrome\n");
}
else{
printf("not palindrome\n");
}
return 0;
}
int main(){
int x;
printf("Enter the number  to check palindrome\n");
scanf("%d",&x);
palindrome(x);
}
