graphics in c and c++

Question

In turbo c 3.2 I am getting

Divide error

and in code blocks IDE I getting error that

initgraph() and closegraph() are refrence at compile time. (I added graphics header and library file in folder of codeblocks).Please give me solution?

the code i written is

#include<graphics.h>
int main()
{
   int a=10,ab;
   initgraph(&a,&ab,"C:\\TURBOC3\\BGI");
   circle(100,200,20);
   closegraph();
   return 0;
 }

It's very hard to tell what you're trying to do and what it wrong. Please include a [Minimal, Complete, and Verifiable example](https://stackoverflow.com/help/mcve). — Marc, Jan 03 '18 at 11:36
Turbo C is ancient history by now. So is the `"graphics.h"` header file and the library. What you learn from using them will have no (or very little) practical bearing on your life later as a programmer. — Some programmer dude, Jan 03 '18 at 11:38
Turbo C was discontinued ages ago. Do yourself a favor and use something else. — klutt, Jan 03 '18 at 11:42
I have colleagues that are younger than that compiler. Please get a book or teacher that teaches this centuries' programming. — nvoigt, Jan 03 '18 at 11:43

@Klutt turbo C discontinued but no IDE supporting graphics. h header file and to manually include it — KD., Jan 03 '18 at 11:48

In addition to the backslash issue in the path, it's extremely unlikely that you are using a 3270 compatible display. Why don't you pass in the address of a with a=0. ab must be set to a requested mode unless you set the driver to autodetect, which will then select the highest available mode. See here.

The path string should be "C:\\TURBOC3\\BGI" (note the double backslashes instead of single backslashes)
I hope this solves the problem. I can't see any other error in code.

Still getting error of "divide error" – KD. Jan 03 '18 at 11:52
Made sure that C:\TURBOC3\BGI is the address of EGAVGA.BGI file ? – Gaurav Singh Jan 03 '18 at 11:55
Yes sure there contains EGAVGA.BGI file at that address – KD. Jan 03 '18 at 11:58
