How Resource Acquisition Is Initialization prevents memory leaks, and how unique_ptr, shared_ptr, and weak_ptr manage ownership.

std::vector, std::map, std::unordered_map, std::set, iterators, and the algorithm functions that operate on them.

A function call transfers control while preserving enough state for the caller to resume.

Follow the key state changes and boundary checks involved in what a function call places in a stack frame.

The heap holds objects whose lifetimes are not tied to one simple lexical scope.

How std::move and rvalue references eliminate unnecessary copies, and when move constructors are called.

How std::thread, std::mutex, and std::atomic work, and the race conditions and memory ordering issues they prevent.
