Palindrome numbers

Question

I'm making a code that checks whether the number is a palindrome or not. Here is my code:

#include <iostream>
using namespace std;

bool isPalindrome(int x) {
//complete the function
int n;
int num;
int digit;
int rev;
n = num;
do {
digit = num % 10;
rev = (rev * 10) + digit;
num = num / 10;

} while (num != 0 );

return 0;
}

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

I'm so close. The only issue is that it only corrects the numbers that are not palindrome, and not the ones that are palindromes. Can someone explain to me why this is happening?

Thank you!

I have made some changes to your code

Answer 2

The bool function is used for return either true = 1 or false = 0

So that's why instead of calculating the reverse of number inside the bool function

I have taken another int return type function named -> calculate

In calculate function I have reversed the digit
And called the reversed value in the bool function to evaluate the expression true or false with the original value

I have checked ✔ ✅ it passes all the test conditions

Hope it helps !
