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.

  1. Macros are powerful tools if used in the right way. However, the following aspects limit the usage of macros. (1) You cannot debug macros; (2) Macro expansion can lead to strange side effects; (3) Macros have no namespace, so if you have a macro that clashes with a name used elsewhere, you get macro replacements where you didn't want them, and this usually leads to strange error messages; and (4) Macros may affect things you are not aware of.

  2. A class/function template refers to a kind of template used to generate template classes/functions. It's just a template but not a class/function, and hence the compiler does not generate any object code for it. A template class/function is an instance of a class/function template. Since it is a class/function, the corresponding object code...
