Armstrong Number Checker in C#

Today I would like to share with you guys a program that is written by a close friend of mind, a fellow software engineer and expert C# developer Mr. Alfel Benvic G. Go he wrote this program we called Armstrong Number Checker using C#. First of all thank you Sir Bon for sharing this program to us. What does the program will do is to ask the user to give a number and then our program will compute the armstrong number based on the given number by our user. Thank you once again Sir Bon for sharing your codes to us.

            while (num > 0)

            {

                remainder = num % 10;

                check = check + (Int32)Math.Pow(remainder, size);

                num = num / 10;

            }

            if (check == n)

                Console.WriteLine(n + " is an Armstrong Number");

            else

                Console.WriteLine(n + " is not an Armstrong number");
