How does C++ realize Maze Game based on easyx

This article introduces the relevant knowledge of "how C++ implements maze games based on easyx". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!
