Today, I will show you how to create a 2D bubble shooter game using C++ and OpenGL. This program will definitely help you learn C++ game development.
The complete source code of the 2D Bubble Shooter Game written in C++ is given below.
/*
This is bubble shooter game developed using C++ programming language and
OpenGL API. Here OpenGL API is used specially for graphics related development
purpose.
