hi every body. i'm new in c# bout book "beginers c#"
and i get stacked on this code:
namespace Ch04Ex06
{
   class Program
   {
      static void Main(string[] args)
      {
         double realCoord, imagCoord;
         double realTemp, imagTemp, realTemp2, arg;
         int iterations;
         for (imagCoord = 1.2; imagCoord >= -1.2; imagCoord -= 0.05)
         {
            for (realCoord = -0.6; realCoord <= 1.77; realCoord += 0.03)
            {
               iterations = 0;
               realTemp = realCoord;
               imagTemp = imagCoord;
               arg = (realCoord * realCoord) + (imagCoord * imagCoord);
               while ((arg < 4) && (iterations < 40))
               {
                  realTemp2 = (realTemp * realTemp) - (imagTemp * imagTemp) - realCoord;
                  imagTemp = (2 * realTemp * imagTemp) - imagCoord;
                  realTemp = realTemp2;
                  arg = (realTemp * realTemp) + (imagTemp * imagTemp);
                  iterations += 1;
               }
               switch (iterations % 4)
               {
                  case 0:
                     Console.Write(".");
                     break;
                  case 1:
                     Console.Write("o");
                     break;
                  case 2:
                     Console.Write("O");
                     break;
                  case 3:
                     Console.Write("@");
                     break;
               }
            }
            Console.Write("\n");
         }
         Console.ReadKey();
      }
   }
}
Can any one explayne to me how dose it works (its a console aplication)??:D
P.S sorry 4 my bad eng.

Your source code is intended to demonstrate for loops and branching via a switch statement.
Your program will display a Mandelbrot set, using plain text characters.

"Each position in a Mandelbrot image corresponds to an imaginary number of the form N = x + y*i, where the real part is x, the imaginary part is y, and i is the square root of -1. The x and y coordinates of the position in the image correspond to the x and y parts of the imaginary number."
