fillpoly example in c

Header file:

    graphics.h

Synopsis:

     void fillpoly(int num, int *points);

     num - number of points

     *points - pointer to an array of intergers(num X 2) and each 

                    pair of points gives a coordinate(x,y) of polygon

Description:

      fillpoly() draws a polygon using the current drawing color, then fill it with current fill style and fill color.

                /* set fill pattern */

                setcolor(i % 12);

                setfillstyle(i, i % 12);

                /* draw a filled polygon */
