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.

Implementing SFINAE

In this recipe, we will learn how to use Substitution Failure Is Not An Error (SFINAE). This recipe is important because, often, we create templates without ensuring the types passed to a template are what we expect. This can lead to unexpected behavior, suboptimal performance, and even buggy, unreliable code.

SFINAE allows us to be explicit about what types we are expecting in our template. It also provides us with a means to change the behavior of our templates based on the types we are provided. The problem with SFINAE for some is that this concept is difficult to understand. Our goal in this recipe is to demystify SFINAE and show how you can use this in your own code.
