Calling a Method by Value Versus by Reference Using output variables

Demo Code

using System;// ww w  .j  a v a 2  s  .  com
class nbr
{
   public void math_routines( double x, out double half, out double squared, out double cubed )
   {
      half = x / 2;
      squared = x * x;
      cubed = x * x * x;
   }
}
class TestApp
{
   public static void Main()
   {
      nbr doit = new nbr();
      double nbr = 600;
      double Half_nbr = 0;
      double Squared_nbr = 0;
      double Cubed_nbr = 0;
      Console.WriteLine("Before method -> nbr = {0}", nbr);
      Console.WriteLine("            Half_nbr = {0}", Half_nbr);
      Console.WriteLine("         Squared_nbr = {0}", Squared_nbr);
      Console.WriteLine("           Cubed_nbr = {0}\n", Cubed_nbr);
      doit.math_routines( nbr, out Half_nbr, out Squared_nbr, out Cubed_nbr );
      Console.WriteLine("After method -> nbr = {0}", nbr);
      Console.WriteLine("           Half_nbr = {0}", Half_nbr);
      Console.WriteLine("        Squared_nbr = {0}", Squared_nbr);
      Console.WriteLine("          Cubed_nbr = {0}", Cubed_nbr);
   }
}
