Write C# program to print number in words

I have used Visual Studio 2012 for debugging purpose. But you can use any version of visul studio as per your availability.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
 
public class csharpExercise
{
    static void Main(string[] args)
    {
        int n, num = 0;
 
        // Reading a number from user
        Console.WriteLine("Enter any number to print in words: ");
        n = Convert.ToInt32(Console.ReadLine());
 
        while (n != 0)
        {
            num = (num * 10) + (n % 10);
            n /= 10;
        }
 
        //print corresponding digit in words till num becomes 0
        while (num != 0)
        {
            switch (num % 10)
            {
                case 0: Console.Write("zero ");
                    break;
                case 1: Console.Write("one ");
                    break;
                case 2: Console.Write("two ");
                    break;
                case 3: Console.Write("three ");
                    break;
                case 4: Console.Write("four ");
                    break;
                case 5: Console.Write("five ");
                    break;
                case 6: Console.Write("six ");
                    break;
                case 7: Console.Write("seven ");
                    break;
                case 8: Console.Write("eight ");
                    break;
                case 9: Console.Write("nine ");
                    break;
            }
            num = num / 10;
 
 
 
        }
        Console.ReadLine();
    }
}

Result:

Enter any number to print in words:
