Overview of this book

C++ has evolved over the years and the latest release – C++20 – is now available. Since C++11, C++ has been constantly enhancing the language feature set. With the new version, you’ll explore an array of features such as concepts, modules, ranges, and coroutines. This book will be your guide to learning the intricacies of the language, techniques, C++ tools, and the new features introduced in C++20, while also helping you apply these when building modern and resilient software. You’ll start by exploring the latest features of C++, and then move on to advanced techniques such as multithreading, concurrency, debugging, monitoring, and high-performance programming. The book will delve into object-oriented programming principles and the C++ Standard Template Library, and even show you how to create custom templates. After this, you’ll learn about different approaches such as test-driven development (TDD), behavior-driven development (BDD), and domain-driven design (DDD), before taking a look at the coding best practices and design patterns essential for building professional-grade applications. Toward the end of the book, you will gain useful insights into the recent C++ advancements in AI and machine learning. By the end of this C++ programming book, you’ll have gained expertise in real-world application development, including the process of designing complex software.

Summary

In this chapter, we've discussed the concept of concurrency and showed the difference between parallelism. We learned the difference between a process and a thread, the latter being of interest. Multithreading allows us to manage a program to be more efficient, though it also brings additional complexity with it. To handle data races, we use synchronization primitives such as a mutex. A mutex is a way to lock the data used by one thread to avoid invalid behavior produced by simultaneously accessing the same data from several threads.

We also covered the idea that an input/output operation is considered blocking and asynchronous functions are one of the ways to make it non-blocking. Coroutines as a part of the asynchronous execution of code were introduced in C++20.

We learned how to create and start a thread. More importantly, we learned how to manage data between...
