How to make a 2D or 3D game in C++?

Answer 1

After completely learning C++,
Learn Windows Programming in C++...

Basics: https://msdn.microsoft.com/en-us/library/windows/desktop/ff381399(v=vs.85).aspx

This will explain you the basics of creating 2D Objects and controlling their Attributes (Module 3 and 4, especially).

As you advance using more such tutorials you'll be able to not just create graphical objects , but make real time moving 3D ones...

This may help you in the future to make your own 3D Game...

Note: Windows Programming gives you access to DirectX...

Hope that helps...
