C programming source code for graphdefaults

#include <graphics.h>
#include <conio.h>
 
main()
{
   int gd = DETECT, gm;
 
   initgraph(&gd, &gm, "C:\\TC\\BGI");
 
   setcolor(RED);
   setbkcolor(YELLOW);
 
   circle(250, 250, 50);
 
   getch();
   graphdefaults();
 
   getch();
   closegraph();
   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.
