After you have a good understanding of pointers, memory management, classes and inheritance, templates, and file io I would move on to working with OpenGL. Its a lot easier, in my opinion, to get started with. Create some games using just simple blocks, spheres, and triangles.

Making a game and making an engine are two completely different things. I wouldn’t recommend developing an engine for some one who knows some basics about c++. First I would start
