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.

Working with classes

Classes make things a lot easier when dealing with objects. They do the simplest necessary thing in OOP: they combine data with functions for manipulating data. Let's rewrite the example of the Product struct using a class and its powerful features:

class Product {
public:
Product() = default; // default constructor
Product(const Product&); // copy constructor
Product(Product&&); // move constructor

Product& operator=(const Product&) = default;
Product& operator=(Product&&) = default;
// destructor is not declared, should be generated by the compiler
public:
void set_name(const std::string&);
std::string name() const;
void set_availability(bool);
bool available() const;
// code omitted for brevity

private:
std::string name_;
double price_;
int rating_;
bool available_;
};

std::ostream& operator<&lt...
