Best site to learn C++?

edX is probably your best bet to learn most programming languages. Otherwise, I'd say pick up some books/e-books and dive right in.

Honestly I wouldn't know because I kinda learned it on my own in the past.

Udemy. I think it is the best site for learning C++ or lua idk.

Try looking tutorials on youtube, youtube helps a lot especially with coding

You have Udemi, but i prefer OpenClassroom, it's basic but OC is the best

I would say udemy the course there are really professional and they are all experinced guru with student Q&A which bring up problem and answer through out their teaching. Many great stuff learn from other student mistake and adopt online course it way better than real life college which is a hassle

People love edX, but I suggest you to go some courses closed by your place; it's always better than online courses

Try UDEMY. They got all the courses you need to be an expert on such topics.

Answer: There is no best site or way to learn it, C++ is not nearly as lit as Scratch or MiT app Inventor, trust me
