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.

The heap under a microscope

In this recipe, we will learn how the heap works in Linux. We will take a deeper look into how Linux actually provides heap memory when you use std::unique_ptr.

Although this recipe is intended for those of you who have more advanced capabilities, it is important as it will teach you what your application does to allocate memory from the heap (that is, using new()/delete()), which, in turn, will show you why heap allocations should never be done from time critical code, since they are slow. This recipe will teach you the skills you'll need when heap allocations are safe to perform and when heap allocations should be avoided in your applications, even if some of the assembly code that we inspect is hard to follow.
