C# Exercise: 68 Hexadecimal and binary

using System;  // Import the System namespace for basic functionality

class Program  // Define the main class
{
    static void Main()  // The entry point of the program
    {
        // Infinite loop to keep asking the user for input until they enter 0
        while (true)
        {
            // Ask the user for a number
            Console.Write("Enter a number (0 to quit): ");
            int number = int.Parse(Console.ReadLine());  // Read the input and convert it to an integer

            // If the number is 0, exit the loop and end the program
            if (number == 0)
            {
                Console.WriteLine("Goodbye!");
                break;  // Exit the loop
            }

            // Display the number in hexadecimal
            Console.WriteLine($"Hexadecimal: {number:X}");

            // Display the number in binary
            Console.WriteLine($"Binary: {Convert.ToString(number, 2)}\n");
        }
    }
