C++ Program to Check Palindrome Number using While loop

C++ program to check palindrome number using while loop. In this article, you will learn that how to make a C++ program to check palindrome number using while loop.

What is Palindrome Number?

A palindrome is a case where if the reverse of any number will be matched correctly with its original integer number, It will be a palindrome.

Palindrome Number Formula

Source Code

// C++ Program to Check Palindrome Number using While loop
#include <iostream>
using namespace std;

int main() {
    int x, r, rN = 0, oN;
    
    // rN - To store the reverse number
    // oN - To store the original number
    // r - To store the remainder
    
    cout << "Enter an integer number::\n";
    cin >> x;
    
    oN = x;

    // reverse number will be stored during iteration
    while (x != 0) {
        r = x % 10;
        rN = rN * 10 + r;
        x /= 10;
    }

    // if original number will match with reverse then palindrome case will be true
    if (oN == rN) {
        cout << "The " << oN << " is a palindrome number.";
    } else {
        cout << "The " << oN << " is not a palindrome number!";
    }
    return 0;
}
