Write a C++ program to check if a given number is a palindrome. A palindrome is a number that remains the same when its digits are reversed.
Question
Write a C++ program to check if a given number is a palindrome. A palindrome is a number that remains the same when its digits are reversed.
Solution
Sure, here is a simple C++ program that checks if a given number is a palindrome:
#include <iostream>
using namespace std;
int main() {
int n, num, digit, rev = 0;
cout << "Enter a number: ";
cin >> num;
n = num;
do {
digit = num % 10;
rev = (rev * 10) + digit;
num = num / 10;
} while (num != 0);
cout << "The reverse of the number is: " << rev << endl;
if (n == rev)
cout << "The number is a palindrome.";
else
cout << "The number is not a palindrome.";
return 0;
}
This program works by reversing the digits of the input number and then comparing the reversed number with the original number. If they are the same, then the number is a palindrome.

Problem StatementSusi loves playing with numbers and exploring their unique properties. One day, she learned about palindromic numbers and decided to write a program to check if a given number is a palindrome or not. Can you help her accomplish this task using a while loop?Note: palindrome is a number that is the same when reversed. For example, 121, 1331, and 45654 are palindromic numbers.Input format :The input consists of a single integer, n, where n is the number that Susi wants to check for palindromic properties.Output format :The output displays one of the following messages:"Palindrome" if n is a palindrome."Not a Palindrome" if n is not a palindrome.Refer to the sample output for the formatting specifications.Code constraints :In this scenario, the test cases fall under the following constraints:11 ≤ n ≤ 106Sample test cases :Input 1 :2552Output 1 :PalindromeInput 2 :1234Output 2 :Not a PalindromeInput 3 :11Output 3 :PalindromeInput 4 :1000000Output 4 :Not a Palindrome
