I’ve been poking around in the open source Corona GitHub repository and thinking about some contributions I’d like to make someday. I’m definitely going to need to bone up on C++.
My general approach to learning all things coding is to buy a bunch of O’Reilly books and watch online videos. Does anyone have any favorite C++ books or online courses to share?
I’d recommend going with a newer edition of Stroustrup along with something like Meyers.
There are a few major conferences, off-hand CppCon and BoostCon (there are others, but I can’t even keep up with these :D), with tons of talks. In particular, CppCon had a “Back to Basics” track this year. This isn’t quite beginner material, but probably safe once you get up and running. The overwhelming majority of presentations are about new or up-and-coming features in the language or its standard libraries, though.
Jason Turner has a podcast, though I only know this from him mentioning it in his talks. But those are good. :) (Look for his Commodore 64 Pong, for instance.)
cppreference is the go-to site to look things up, once you sort of know your way around.
Something like Sedgewick would be good too. Lots of little samples in those.
I was about to ask this very same question, so thank you both. 
I have an older edition of this book by Michael Dawson that I thought I’d give a quick read and then pursue some more advanced books or courses, like GameDev TV’s C++/Unreal tutorials (that I’ve already bought and paid for in some Humble Bundles, but never got to open… yet).
Edit: Oh, and there’s this great channel with plenty of useful tutorials and great insights (to C++ and other stuff) - https://www.youtube.com/watch?v=18c3MTX0PK0&list=PLlrATfBNZ98dudnM48yfGUldqGD0S4FFb
Another one with several snippets and covering useful ideas: Game Programming Patterns
Great suggestions, keep’em coming!
I’ve worked through so many programming samples in C (especially my A.I. and game engine physics books) that I feel like I have a basic concept but it’s helpful to have a direction to put my energy into as I “officially” start this new endeavor.
On the C front you also have Lua’s API as well as its source code.
