Do you have any idea what are those games in c++ that are easy to do?

Answer 1

You seemed to have just started C++ and already wrote 3 questions on how to make a game in it.
I strongly recommend to not start with graphical user interfaces in C++, but rather make a simple console application (based around input and output)…
As this is hardly possible in SoloLearns way of dealing with inputs, you might want to try a “proper” IDE like CodeBlocks.

Moreover i would noy really start with complex games at all, maybe some kind of guessing game (e.g. there is a secret number and after each input the programm tells to go higher or lower). But honestly the praxice exercises of SoloLearn should be good as well, especially in the beginning… I needs its time to learn programming especially games in raw C++ without an game engine

Answer 2

Ohh and really: 3 questions in a row all about the same thing even if the questions are slightly different is close to spam…
What about instead having one question where you go into more detail of what you want and why, so you can get a good answer?
