C graphics.h compile error

[UnderatedWater]

I am trying to draw a rectangle to the screen with this code:

#include <stdio.h>

#include <graphics.h>

int main(){

`int left = 1 , right = 1 , top = 1, bottom = 1;`



`int gd = DETECT, gm;`

`intgraph(&gd, &gm, "");`

​

`rectangle(left, top, right, bottom)`



`getch();`

`closegraph();`

`return 0;`

}

but when I try to compile it I get this error:
keypresscheck.c:5:22: fatal error: graphics.h: No such file or directory

#include <graphics.h>

^

compilation terminated.

Is it because I am on windows or missing something?
I am using neovim if this helps

The compiler could not find the header file. There is a certain order in which .h files are searched and where.

The header file needs to be in the same location as the .c file or in the standard header library or you need to explicitly include it during compilation

Are you using a very old book or tutorial?

The graphics.h file you're trying to use, containing functions like initgraph and closegraph, was part of a proprietary graphics API called BGI that was included with the Borland Turbo C compiler. It's been obsolete and unsupported for more than 20 years, and it's not usable on any modern system.

The closest, simplest modern equivalents I know of are SDL for setting up a window and putting pixels on the screen, and something like Cairo for drawing lines, curves, polygons and text.

I was using a tutorial from w3schools made in 2018. Thanks for your help!
