Thank you, Carlo ;)

Solution 4 try: C# Expand ▼ Copy Code class Program { const int N = 20; static void Main() { char [, ] circle = new char[2*N+1, 2*N+1]; double phi, dphi = 0.5 / N;

     phi = 0.0;

     for (int y = 0; y < 2*N+1; y++)
       for (int x = 0; x < 2*N+1; x++)
         circle[y, x] = '0';

     while (phi <= 2*Math.PI)
     {
       int x = (int) Math.Round( N + N * Math.Cos(phi));
       int y = (int)Math.Round(N + N * Math.Sin(phi));
       circle[y, x] = '1';
       phi += dphi;
     }

     for (int y = 0; y < 2*N+1; y++)
     {
       for (int x = 0; x < 2*N+1; x++)
         Console.Write(circle[y, x]);
       Console.Write('\n');
     }
   }
