Moving a circle in C graphics on Visual Studio

[loismustdie]

I really need help guys.. I started C++ yesterday.. managed to make a circle.. How do I move it? ( I need to make a simulation of acceleration.)

#include "graphics.h"
#include "winbgim.h"

void main()
{
	initwindow(1080, 720);

	circle(100, 100, 50);

	getch();
}

Draw the circle again but with the backgroundcolor to delete it. Then draw it on a different location.

void main(void)
{
  int x = 100, y = 100, radius = 50;

  initwindow(1080, 720);
  setcolor(GREEN);
  while (!kbhit())
  {
    circle(x, y, radius);
    delay(200);
    setcolor(BLACK);
    circle(x, y, radius);
    x += 10;
    setcolor(GREEN);
    circle(x, y, radius);
  }
	
}

Play around a bit with the delay and move distance.

If you just started C++ then I suggest you find a modern compiler and a modern graphics package. That graphics package you're using is so outdated it should be abandoned.

WinBGI is from 2004 - is this really so outdated?
Can you recommend a more modern and easy-to-use graphics package?

Yes, it is outdated, 2004 is a long time ago when talking about computer graphics programs. Also this started as a partial hack of the Borland DOS BGI graphics library that had become outdated.

You can look into SDL, OpenGL, Glew, to name a few.

But since the OP stated that he is just starting his C/C++ programming journey I would recommend staying away from graphics until he masters the core language.
