Spiral maps.

I rewrote the program for calculating arcs of various radii (which are needed for drawing these arcs on the "Heroes III" map).
I adapted the DOS version for Windows.

/*   p1
      Visual C++ 6.0
      Console application
      Radius   */

#include 
#include 

main ()
{
   int a, b, c, d;
   FILE *g;

   /*   a - radius for which the calculation is performed
          b - maximum value for which the square root is calculated
          c - counter
          d - calculated value of the circle boundary   */

   g = fopen ("1.txt", "w");
   for (a = 1; a < 61; a++)   /*   outer radius 1/8 of the circumference   */
   {
      b = (int) (a / sqrt (2) + 2);   /*   upper limit of calculations   */
      fprintf (g, "r = %i\n", a);
      for (c = 0; c < b; c++)
      {
         if (c == a) break;
         d = (int) (sqrt (a * a - c * c - .0001) + 1);
         if (d < c) break;
         if (d == a) continue;
         fprintf (g, "%i - %i\n", c, d);
      }

      fprintf (g, "\n");
   }

   fclose (g);
   return 0;
}
