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 👇 https://code.sololearn.com/cmxyn2sexKeU/?ref=app

#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; }
