hi!
i tried to run the following program in BORLAND C++ version 5.02..
#include<stdio.h>
#include<graphics.h>
#include<string.h>
#include<math.h>
#include<conio.h>

else

}

getch();
cleardevice();
closegraph();
}
but it tells me that BGI graphics is not supported under windows..
what does this mean????????
i tried googling it, but couldn't understand how to solve it, all i came to know is that there is some other header file to be used..
now what should i do?.. if i am to change the header file, then where to get the new header file from? and how to use this??
i am new to graphics programming in Borland c++, so i am not able to understand much... hence, if possible plz give me the exact procedure to follow..
plz help me out..
