Answer 1

1) You are not returning anything if you *if* statement at like 12 is false.

Possible Fix: add a simple "return false" there

2) you are messing up your original number *x* during reversing it which will always fail the condition (x == reversenumber)

Possible Fix: do the operations on a duplicate instead

Here is how your program will look after applying all the fixes 👇

Answer 2

Thank you. Yes, I also tried your version of the duplicate before... :)

Answer 3

#include <iostream>
using namespace std;

bool isPalindrome(int n)
{
int x = n;
int reversedNumber = 0, remainder;
while(x != 0)
{
remainder = x%10;
reversedNumber = reversedNumber*10 + remainder;
x /= 10;
}
return n == reversedNumber; //check if inputted number = reversedNumber
}

int main() {
int n = 111;

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