Overview of this book

C++ High Performance, Second Edition guides you through optimizing the performance of your C++ apps. This allows them to run faster and consume fewer resources on the device they're running on without compromising the readability of your codebase. The book begins by introducing the C++ language and some of its modern concepts in brief. Once you are familiar with the fundamentals, you will be ready to measure, identify, and eradicate bottlenecks in your C++ codebase. By following this process, you will gradually improve your style of writing code. The book then explores data structure optimization, memory management, and how it can be used efficiently concerning CPU caches. After laying the foundation, the book trains you to leverage algorithms, ranges, and containers from the standard library to achieve faster execution, write readable code, and use customized iterators. It provides hands-on examples of C++ metaprogramming, coroutines, reflection to reduce boilerplate code, proxy objects to perform optimizations under the hood, concurrent programming, and lock-free data structures. The book concludes with an overview of parallel algorithms. By the end of this book, you will have the ability to use every tool as needed to boost the efficiency of your C++ projects.

Why C++?

Let's begin by exploring some of the reasons for using C++ today. In short, C++ is a highly portable language that offers zero-cost abstractions. Furthermore, C++ provides programmers with the ability to write and manage large, expressive, and robust code bases. In this section, we'll look at what we mean by zero-cost abstractions, compare C++ abstraction with abstraction in other languages, and discuss portability and robustness, and why such features are important.

Let's begin by getting into zero-cost abstractions.

Zero-cost abstractions

Active code bases grow. The more developers working on a code base, the larger the code base becomes. In order to manage the growing complexity of a code base, we need language features such as variables, functions, and classes to be able to create our own abstractions with custom names and interfaces that suppress details of the implementation.

C++ allows us to define our own abstractions but it also...
