Hey man, i had the same problem 2 weeks ago…
The only thing you can do is to read through the documentation here: (Programming Guide Parts) https://docs.unrealengine.com/latest/INT/Programming/index.html
There are 5 short, but in my opinion, good tutorials which teach some of the basics every c++ programer for UE4 needs to know: Unreal Engine CPP Programming Tutortials | Unreal Engine 5.1 Documentation
And just read the documentation i guess… thats how i do it right now
