how can i use graphics.h?

[Cambalinho]

heres an test code:

#include <graphics.h>
#include <string>

using namespace std;
int main()
{
   int gd = DETECT, gm;
   int x = 320, y = 240, radius;
    char a[]="c:\\tc\\bgi\\";
   initgraph(&gd, &gm, a);

   for ( radius = 25; radius <= 125 ; radius = radius + 20)
      circle(x, y, radius);

   getch();
   closegraph();
   return 0;
}

when i execute, i get a memory leak.. why?
is because i must use an array of char's?

How do you know you have a memory leak?

Why do you include string, shouldn't it be string.h?

"How do you know you have a memory leak?"
when i execute, instead show the circle, don't show anything and the windows 7 give me a window with a message that stops responding and then close my program.
what is wrong?
if i can execute the problem isn't on my linker options(i add the lbbgi.a and "-lbgi -lgdi32 -lcomdlg32 -luuid -loleaut32 -lole32" linker options\commands

"process returned 255 (0xFF)"

It's not using any of that stuff. You're using a library developed in 1991 for use on MS-DOS. It uses CGA, EGA, and probably VGA too, but that's about it. It predates Window 3. It is not a route for programming Windows graphics.

maybe these one: http://winbgim.codecutter.org
is outdated.
thank you so much. i will test another one. thank you

now works fine... i have found these tutorial: https://erainnovator.com/how-to-include-graphics-h-in-codeblocks/
readers: please read it until the end. because if we can't get the results, we can add the other library.
thank you so much for all
