Why it always say no even no. Is palindrome?

Question

#include<iostream>
using namespace std;

bool isPalindrome(int num){
int reverse=0;
int b;
while(num!=0){

b=num%10;
reverse=reverse*10+b;
num=num/10;
}
if(num==reverse)
return true;

else
return false;
}
int main(){
int n;
cin>>n;
if(isPalindrome(n))
cout<<"yes";
else
cout<<"no";
}

Answer 1

in function original num becomes 0 after loop so you are comparing
if ( 0 == reverse) so it false expect for 0 input..
Copy original num value, use copy in loop..

Answer 2

Why it become zero after loop

Answer 3

You are using num inside loop.
And modifying it's value by num=num/10 . Stop looping when num==0
Means when num!=0 loop continues otherwise stops.. Is not it?

Thanks
