✅ Palindrome Check for Numbers in C++

In this tutorial, you'll learn how to check whether a number is a palindrome using C++. This logic is essential in many programming challenges and interviews.

📘 What is a Palindrome?

A palindrome is a number that remains the same when its digits are reversed. For example, 121 and 1331 are palindromes, but 123 is not.

📄 C++ Program: Palindrome Number Checker

#include <iostream>
using namespace std;

int main() {
    int number, reversed = 0, original, remainder;

    cout << "Enter a number: ";
    cin >> number;

    original = number;

    while (number != 0) {
        remainder = number % 10;
        reversed = reversed * 10 + remainder;
        number = number / 10;
    }

    if (original == reversed) {
        cout << original << " is a Palindrome.";
    } else {
        cout << original << " is not a Palindrome.";
    }

    return 0;
}
      

✅ Sample Output

Enter a number: 121
121 is a Palindrome.
    

🧾 Explanation

• The user inputs a number.
• We reverse the number using modulo (%) and division (/).
• If the original number matches the reversed version, it is a palindrome.
