I think you need to check the documentation. And why do you need python in order to run a C++ program?

Drawing means to output some pixel colors with coordinates on the monitor. One way is to draw yourself or use some library or classes.

The basics are explained in the article GDI Drawing and Printing and some advanced class High-speed Charting Control.

You can also draw with python, but I only know the turtle library. But I think it is much slower than C++.

Solution 3

I don't want to draw. I have points I want see how these point scatter in the x-y plane.
It the points won't have a specific shape.Points may represent line or cluster.

If you do not draw the points, how do you expect to see them on the screen?

This is not a solution.
