C programming source code for graphdefaults

#include <graphics.h>
#include <conio.h>
   int gd = DETECT, gm;
   initgraph(&gd, &gm, "C:\\TC\\BGI");
   circle(250, 250, 50);
   return 0;

In the above program we have first changed the drawing color to RED and background color to YELLOW and then drawn a circle with (250, 250) as center and 50 as radius. When the user will press a key graphdefaults is called and both drawing and background color will be reset to their default values i.e. WHITE and BLACK respectively. See colors in c graphics.
