I am a total Beginner in C++ and programming generaly.

I have watched a couple of hours tutorals of C++ and read alot about it(Could you recomend some tutorials?), but what I´ve come across and couldn´t understand was Librarys.

I want to develop games in C++(I think, it seems most interestning atm). I can understand that much that I need a library for game programmig in C++, but I dont know much about, what A library is specificly, and where to find these librarys.

Also, I´ve read that Lua should be good to script the games with. I would like to know if this is true? If its true, I would like to know where to find tutorials for Lua? If not true, what is good then?

Thank you for your time. This is my first question here. I apoligize if it wasen´t a propper question for this website, or if the english was bad. I still hope you can give me some kind of answer and/or reponse.
