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.

Exploring function and class templates

We will start this section by introducing the syntax of function templates and their instantiations, deductions, and specializations. Then, we will move on to class templates and look at similar concepts, as well as examples.


So far,when we have defined a function or a class, we have had to provide input, output, and intermediate parameters. For example, let's say we have a function to performs the addition of two int type integers. How do we extend this so that it handles all the other basic data types, such as float, double, char, and so on? One way is to use function overloading by manually copying, pasting, and slightly modifying each function. Another way is to define...
