Armstrong Number in C Sharp

by

Armstrong Number

A number equal to the sum of the cubes of its digits is called an Armstrong number.

For example,

0, 1, 153, 370, 371 and 407.

Explanation:

153 = (1*1*1) + (5*5*5) + (3*3*3) = 1 + 125 + 27 = 153

Example:

using System;  
  public class Example  
   {  
     public static void Main(string[] args)  
      {  
       int  num, x, sum=0, y;      
       Console.Write("Enter a Number: ");      
       num = int.Parse(Console.ReadLine());     
       y = num;      
       while(num>0)      
       {      
        x = num%10;      
        sum = sum + (x*x*x);      
        num = num/10;      
       }      
       if(y==sum)      
        Console.Write("Armstrong Number!!");      
       else      
        Console.Write("Not an Armstrong Number!!");      
      }  
  }

Explanation:

In the above example, we are displaying the C# program to check an Armstrong Number.
