Advanced C++ Programming Cookbook

By: Dr. Rian Quinn

Overview of this book

If you think you've mastered C++ and know everything it takes to write robust applications, you'll be in for a surprise. With this book, you'll gain comprehensive insights into C++, covering exclusive tips and interesting techniques to enhance your app development process. You'll kick off with the basic principles of library design and development, which will help you understand how to write reusable and maintainable code. You'll then discover the importance of exception safety, and how you can avoid unexpected errors or bugs in your code. The book will take you through the modern elements of C++, such as move semantics, type deductions, and coroutines. As you advance, you'll delve into template programming - the standard tool for most library developers looking to achieve high code reusability. You'll explore the STL and learn how to avoid common pitfalls while implementing templates. Later, you'll learn about the problems of multithreaded programming such as data races, deadlocks, and thread starvation. You'll also learn high-performance programming by using benchmarking tools and libraries. Finally, you'll discover advanced techniques for debugging and testing to ensure code reliability. By the end of this book, you'll have become an expert at C++ programming and will have gained the skills to solve complex development problems with ease.

Declaring noexcept

C++11 introduced the noexcept keyword, which, besides simplifying how exceptions were used in general, also included a better implementation of C++ exceptions that removed some of their performance hits. However, this doesn't mean that exceptions do not include overhead (that is, performance penalties). In this recipe, we will explore how exceptions add overhead to an application and how the noexcept keyword can help reduce these penalties (depending on the compiler).

This recipe is important because it will demonstrate that if a function doesn't throw an exception, then it should be marked as such to prevent the additional overhead regarding the total size of the application, resulting in an application that loads faster.
