when i run the program as below,there are so many errors,i have downloaded
the CLGdiDevpak through webupdate.i really found some mistakes in the header
file <winbgi.h>,but after i correct there basic mistakes and compile it ,there
are still errors.this time i don't know what i should do.the program as
following:

Code:

---

/*    name.c ... this program is quoted from Dev-cpp/Templates/consoleGdi*/

#include <winbgim.h>

main()

{

        initwindow(640,480);

        setcolor(WHITE); 

        circle(320,240,100);

        getch(); 

        closegraph();     

        return 0;

}

what can i do ?i am learning C language by myself,so please say it clearly.
thx thx thx thx thx thx thx thx thx thx....................

Just a guess, but anything windows usually begins with

#include <windows.h>

Are there any examples which come with the package to look at and try yourself
