Introduction

In the previous chapter, we covered different types of dependencies and coupling in C++. We looked at how common API design patterns and idioms can be implemented in C++ and what data structures are provided by Standard Libraries, as well as their efficacy. We also learned how to work with functional objects, lambdas, and captures. This knowledge will help us learn how to write clear and efficient multithreaded programs.
