Program to Print Armstrong numbers in C

C# Program to Print out all Armstrong numbers between 1 and 500

Program Statement:

Write a program to print out all Armstrong numbers between 1 and 500. If sum of cubes of each digit of the number is equal to the number itself, then the number is called an Armstrong number. For example, 153 = (1 * 1 * 1) + (5 * 5 * 5) + (3 * 3 * 3)

Solution:

 public class armstrong
 {
 int x, a, res, sum = 0;
 public void find()
 {
 Console.WriteLine(" All Armstrong Numbers between 1 and 500 ");
 for (x = 1; x <= 500; x++)
 {
 a = x;
 while (a != 0)
 {
 res = a % 10;
 a = a / 10;
 sum = sum + (res * res * res);
 }
 if (x == sum)
 Console.Write(" {0} ", x);
 sum = 0;
 }
 Console.WriteLine(" ");
 }
