Question

I started learning c++
I would like to know if i need to learn anything else for coding cheats
is it stuff like CreateToolhelp32Snapshot function?

CreateToolhelp32Snapshot is a function.

I guess you don't need any additional information
For any target you can do an universal solution or direct one
I always doing universal solutions and learn everything can be useful, but I think it's wrong
Atleast at the start you need only important things
Read articles, try to repeat and only writing code can help you understand
Also I want to warn you - coding cheats takes a lot of resources, atleast reverse engineering
So don't you take a hard games with commercial anticheats at the first time, try something basic
P.S. CreateToolhelp32Snapshot is a function that snapshots processes/modules/threads
