[Q] C++/Memory hacking related question

Hello!

This question is mostly intended for people that know about C++, reverse engineering and memory stuff. Okay, so, basically:

I think most of us started from some basic things. Well, I did start from Assault Cube. It's easy. Cheat Engine + C++ / C#. But now, I wanna move one to some other games. I found a game called "Pumping Simulator 2" (everything is cracked). I found the money address and value, managed to have fun with it, write an external trainer for that game. But, I failed to use pointers (there's 1+ pointers and a lot of addresses that lead to the value and address). Could some either tell me, or, please, teach me how to handle those?

It would be greatly appreciated. Thanks!
