C++ Program to Check if Given Number is Palindrome or Not using While Loop

Write C++ Program to Check if Given Number is Palindrome or Not using While Loop

// CPP Program to Check if given number is palindrome or not using While Loop

#include <iostream>

using namespace std;

int main()
{
	long int n, ans = 0;

	cout << "Enter the number:--> ";
	cin >> n;  //User input:-422

	long int temp = n;

	while(n != 0)
	{
		int remainder = n % 10;  //2  //2  //4
		ans = ans * 10 + remainder;  //2  //22  //224
		n = n / 10;   //42  //4
	}
	if(temp == ans)
	{
		cout << "The given number is palindrome";
	}
	else
	{
		cout << "The given number is not palindrome";
	}

	return 0;
}

Output:

Enter the number:--> 456
The given number is not palindrome

Enter the number:--> 121
The given number is palindrome
