How to draw Circle in C Using Grahpic

[NotAceGG]

#include<graphics>
main()
{
int gd=0,gm;
initgraph(&gd,&gm,"");
circle(100,80,20);
closegraph();
}
 Error:fatal error: graphics: No such file or directory

Are you sure the library is called graphics and the files for that library are installed on the computer?

Tell a big more. Which compiler, OS and what else we would need to know to duplicate this issue.

Line 4 looks to be an issue. See what they used at https://www.geeksforgeeks.org/draw-circle-c-graphics/

Try changing line 1 to:

#include <graphics.h>

In C, it's conventional to use ".h" as a suffix for a C header file; and that is the name of the Borland Graphics Interface header that defines functions named initgraph(), circle() and closegraph().

It's not a Standard C header, though, so unless you have an old copy of Turbo C or compatible, or have installed a compatible library on a modern compiler, that won't help. If you're in a class that gave you a setup procedure to install C on your computer for classwork, then fixing the include directective should get you started.

You may need other headers at some point. I include both <stdio.h> and <stdlib.h> in practically every C program I write. Also, programs that use <graphics.h> will also often use low-level console functions defined in <conio.h>, which is another common nonstandard header from last century. If you see something telling you to use getch() or kbhit(), then you probably need <conio.h> included.
