Modern C++ code now looks very different to even C++11 code which is considered to be the start of modern C++. "A Tour of C++" which has already been recommended is probably a good start to get back in the game. I think there was a new version coming out, but not sure what the current status about this is. [https://en.cppreference.com](cppreference.com) https://en.cppreference.com](cppreference.com) is a good resource for me. It has documentation regarding the new standards as well and up to C++20 the examples are mostly complete, at least for the relevant things. I can also recommend watching the "Back to Basics" talks on the CppCon youtube channel and once you are more familiar also the regular talks. They are great resources about practical topics. Jason Turner's C++ Weekly videos are also a great resource. They are usually 10-15 minutes long videos that give you a good start to think about. Great way to learn something new every week.
