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. Computer memory can be described as a single concept – the Dynamic RAM (DRAM), or as a combination of all the memory units that the computer contains, starting with the registers and cache memory, and ending with the hard drive. From the programmers' perspective, DRAM is of the most interest because it holds the instructions and data of the program running in the computer.
  2. Virtual memory is an approach to efficiently manage the physical memory of the computer. Typically, the operating system incorporates virtual memory to handle memory accesses from programs and to efficiently allocate chunks of memory to particular programs.
  3. In C++, we use the new and delete operators to allocate and deallocate memory space.
  4. delete deallocates the space allocated for a single object, while delete[] is used for dynamic arrays and frees all the elements of the array on the...
