static void Main(string[] args) { int num1,num2, n, sum, r; Console.Write("Enter positive number1 :"); num1 = Convert.ToInt32(Console.ReadLine()); Console.Write("Enter positive number2 :"); num2 = Convert.ToInt32(Console.ReadLine()); Console.WriteLine("Armstrong Number from {0} to {1}",num1,num2); for (int i = num1; i <= num2; i++) { sum = 0; n = i; while (n != 0) { r = n % 10; sum = sum + (r * r * r); n = n / 10; } if (i == sum) Console.WriteLine(i); } Console.ReadKey(); } |
