What do you need to know to create a 2D game?

Question

Programming

Hello.
Now I'm learning C++ on my own. At one of the subjects, by the end of the semester, they were asked to write some kind of program or game. I would really like to create a game on account of completing the task (I think this is a useful experience).
What you need to know to be able to write: 1 - arcade, 2 - RPG (not of great complexity).
Graphics - 2D.
Thanks in advance!

Answer 1

It is best for a beginner to learn how to use any game engine. For example, HGE . Enough, light, sound and graphics with image loading included, good documentation and examples that immediately make it clear what's what. Of the minuses, it is only under Windows and DirectX. You can also learn OpenGL from the "Red Book of OpenGL", tons of lessons and examples. But the second option is really longer and more difficult. If you want to do something fun in 30 minutes, then find a good and lightweight 2D engine.
Good luck

Answer 2

You can also try to implement Conway's "Life". I once did on openzhl. pretty simple and fun.
