How to check if a given number is a Palindrome in C#

C#

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Palindrome_Number_Checker
{
    class Program
    {

static void Main(string[] args)

{

int num, rem, temp, sum = 0;

Console.Write("Enter a Number : ");

num = int.Parse(Console.ReadLine());

temp = num;

while (num > 0)

{

rem = num % 10;

num = num / 10;

sum = sum * 10 + rem;

}

Console.WriteLine("Reverse of the number is : " + sum);

if (temp == sum)

Console.WriteLine("Number is Palindrome");

else

Console.WriteLine("Number is not Palindrome");  // Output: Enter a Number : 121 Reverse of the number is : 121 Number is Palindrome  // Output: Enter a Number : 123 Reverse of the number is : 321 Number is not Palindrome  // Output: Enter a Number : 1221 Reverse of the number is : 1221 Number is Palindrome  // Output: Enter a Number : 1234 Reverse of the number is : 4321 Number is not Palindrome

🤖 Code Explanation

The program takes an integer input from the user and stores it in the variable num. Then, a copy of the original number is stored in the variable temp.

The while loop calculates the reverse of the number and stores it in the variable sum.

Finally, the if-else statement checks whether the number is equal to its reverse or not. If it is equal, then it is a palindrome number, otherwise, it is not.
