I’ve been wanting to learn C++ as well. I am very experienced with JavaScript, and also am very fluent with Arduino. I’ve messed around with actual C++ before but I get lost with all the pointers, header files, and memory allocation stuff.
Are there any resources y’all would recommend to someone who has all of the programming fundamentals, but wants to learn the specifics of C++?
My advice would be to learn C first (or at least develop a good understanding of it). It’s extremely important to understand how memory works in C so that you can understand pointers in C++; and also important to understand how functions work so you can understand classes and methods in C++. I would go through The C Programming Language. It’s fairly concise and while you don’t have to go through it cover to cover, you should at least understand the chapters on structs, pointers and functions (up to chapter 6, I believe).
(Note that the wikipedia link that I posted above has a link to the full text of the book in pdf format.)
The reason why I think it’s important to understand C is because when you learn C++, then you’ll understand how the language abstracts over a lot of the lower-level functionality in C. new in C++ supplants malloc in C for example, and your understanding of functions in C will map to more complicated concepts like constructors, destructors, copies, methods, and operators in C++. At this point, I would probably start learning how classes in C++ work. They’re basically structs with private member variables and methods defined in the scope of the class. learncpp.com, is the best reference that I’m aware of (it’s very thorough, which makes for a pretty slow read, but you’ll understand it very well). I would probably start with chapter 14 (introduction to classes), and then go back to the earlier chapters to fill in the gaps, but this is more dependent on how you think you learn best.
Be aware though, that if you don’t have existing experience with OO development, then C++ is (in my opinion) not a great language to start learning it, because a lot of it is hacked on top of C and implemented in arcane ways in order to maintain compatibility with C. The first language I learned was Java, and it was really helpful to have that as a background for when I learned C/C++. I’m only familiar with Javascript on a procedural programming level, so I’m not aware of its OO functionality or how well that will translate to C++, but hopefully it works out.
Piggybacking on this:
