Answer 3

Well in general you can do anything. The software of Spacex' Falcon rocket is completely written in c++. So you could even shoot a car into space with c++ (not purely with c++ but I guess you get the point ^^)
And for your benefit: you can do usable things with just a basic knowledge. Like a password generator.

Answer 4

Do you mean in general or specific for your benefit?
