Palindrome Help

Question

What am I doing wrong here?

#include <iostream>
using namespace std;

bool isPalindrome(int x) {
//complete the function
int digit;
int rev=0;

while(x!=0){
digit=x%10;
rev=(rev*10)+digit;
x/=10;
}
if(x==rev)
return true;
}

int main() {
int n;
cin >>n;

if(isPalindrome(n)) {
cout <<n<<" is a palindrome";
}
else {
cout << n<<" is NOT a palindrome";
}
return 0;
}

You are changing original value so x would be 0

Store x in a temp variable before using it then compare temp variable with rev

also you missed return in else part

if (temp == rev)
return true;
else
return false;

OR

return (temp == rev);
