Catching Up on C++?


Hi folks, up until 2013, I worked as a C++ developer but moved on to web technologies. In the last decade or so, the language and its features have moved on significantly; when I left, C++11 had barely made its way into compilers, so you could say I'm quite behind on the times.

This is probably a stretch, but since I want to get my feet wet in C++ again, is there some resource that could help me catch up on new features and things worth learning? I would love to avoid reading through reams of standards, but if that's it, that's it.

Many thanks in advance.

Read through https://www.learncpp.com. You'll get a complete refresher on the language, but it will be using modern C++ stuff (modern in this case means C++17).

For C++20 and newer, honestly, the only big feature that I ever use is concepts, although I do also use the new struct initialization syntax[0].

Just go through this https://github.com/AnthonyCalandra/modern-cpp-features and you should be fine.

If you also like thorough explanations and graphs, there's https://hackingcpp.com/ that could answer many questions you might have.

By the way, just in case, bookmark this online C++ reference https://eel.is/c++draft/ for diving in deep waters.

Good luck!

Tour of C++ 3rd Edition [0] would be a good start.
