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.

Concurrency and Multithreading

Concurrent programming allows the creation of more efficient programs. C++ didn't have built-in support for concurrency or multithreading for a long time. Now it has full support for concurrent programming, threads, thread synchronization objects, and other functionality that we will discuss in this chapter.

Before the language updated for thread support, programmers had to use third-party libraries. One of the most popular multithreading solutions was POSIX (Portable Operating System Interface) threads. C++ introduced thread support since C++11. It makes the language even more robust and applicable to wider areas of software development. Understanding threads is somewhat crucial for C++ programmers as they tend to squeeze every bit of the program to make it run even faster. Threads introduce us to a completely different way of making programs...
