The C++ programming language is large and complex. It has many useful features to manage its code structure, performance, and safety, and with each new version acquires more. That makes it difficult to learn in detail. Resources listed in the tables below provide a lot of help with both basics and details. As new C++ Bites arrive, that will become even better - easier to learn and they will become a good source for example code. C++ Highs and Lows
Code shown above on the right demonstrates side effects, something you usually avoid as that makes it harder to reason about the behavior of your program. It's included here to see a bit about how the C++ object model works. Callers of this function see changes to the value of the passed reference target. Because the argument is a reference, passed by reference, callers will also see a change of the target object referred to in the input. The object change happens at line 44. Since the object is held by a std::unique_ptr, the original object is destroyed by the end of execution of line 44. The new object will be destroyed by the time the caller's scope ends. C++ lets you do subtle operations that require care to implement correctly, as in this example. The purpose of this track is to help you acquire the skills to do that. The best way is to avoid subtle code like this, perhaps by passing a const ref and returning the desired result with a move operation. This page has references to things you need to quickly start programming with C++ and will eventually include a broad set references to the important parts of the language.

You can find videos covering some of the topics in Table 1. using the "Resrcs" dropdown in the top menu. Experienced developers will find a lot of language details in the C++ Story and, as the Bites arrive, there too.
