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.

Typecasting with smart pointers

In this recipe, we will learn how to typecast using std::unique_ptr and std::shared_ptr. Typecasting allows you to convert one type into another. This recipe is important as it demonstrates the proper way of handling typecasting with std::unique_ptr and std::shared_ptr when attempting to convert the smart pointer's type (for example, when upcasting or downcasting with virtual inheritance).

Getting ready

Before beginning, please ensure that all of the technical requirements have been met, including installing Ubuntu 18.04 or higher and running the following in a Terminal window:

> sudo apt-get install build-essential git cmake

Once you have done this, open a new Terminal. We will use...
