Description:

In my previous posts I have explained various topics like Get site visitor count in asp.net

Now in this post, I will explain how to check whether the number is Armstrong or not.

Armstrong number is a number which is equal to the sum of cubes of its own digits. For example 0, 1, 153, 370, 371 and 407 are the Armstrong numbers.

Now create Console Application in Visual Studio and write below lines of code in it.

using System;

namespace DotNetK
{
    class Program
    {
        static void Main(string[] args)
        {
            // C# program to check whether the number is Armstrong or not

            int _Number, r, sum = 0, temp;
            Console.Write("Enter the Number= ");
            _Number = int.Parse(Console.ReadLine());
            temp = _Number;

            while (_Number > 0)
            {
                r = _Number % 10;
                sum = sum + (r * r * r);
                _Number = _Number / 10;
            }
            if (temp == sum)
                Console.Write("It is Armstrong Number.");
            else
                Console.Write("Not An Armstrong Number.");

            Console.ReadKey(); // To hold the console screen.
        }
    }
}
