palindrome end of project, c++

Question

I personally prefer the "string based" based path to completing this project, however this is only after I failed to adapt the crazy maths solution i found off the internet, I'm hoping someone can point out where I've gone wrong in trying to solve the bool type problem.

#include <iostream>
using namespace std;

bool isPalindrome(int x) {
int num, digit, rev;
x = num;

do
{
digit = num % 10;
rev = (rev * 10) + digit;
num = num / 10;
} while (num != 0);

if (x == rev)
{
return true;
}
else
{
return false;
}

}

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

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

Answer 1

Hi! for a better understanding of how your code works, please use the "codes" section { }. place it there, make it pubic, and paste the link here

Answer 2

The assignment

x = num;

should be the other way round, i.e.

num = x;

and you need to initialize "rev" to 0, C++ does not do so automatically for you.
Also, you can shorten your return statement to

return ( x == rev );
