Overview of this book

C++ is a highly portable language and can be used to write both large-scale applications and performance-critical code. It has evolved over the last few years to become a modern and expressive language. This book will guide you through optimizing the performance of your C++ apps by allowing them to run faster and consume fewer resources on the device they're running on without compromising the readability of your code base. The book begins by helping you measure and identify bottlenecks in a C++ code base. It then moves on by teaching you how to use modern C++ constructs and techniques. You'll see how this affects the way you write code. Next, you'll see the importance of data structure optimization and memory management, and how it can be used efficiently with respect to CPU caches. After that, you'll see how STL algorithm and composable Range V3 should be used to both achieve faster execution and more readable code, followed by how to use STL containers and how to write your own specialized iterators. Moving on, you’ll get hands-on experience in making use of modern C++ metaprogramming and reflection to reduce boilerplate code as well as in working with proxy objects to perform optimizations under the hood. After that, you’ll learn concurrent programming and understand lock-free data structures. The book ends with an overview of parallel algorithms using STL execution policies, Boost Compute, and OpenCL to utilize both the CPU and the GPU.

Preface

C++ of today provides programmers the ability to write expressive and robust code while still having the ability to target almost any hardware platform or real-time requirements. This makes C++ a unique language. Over the last few years, C++ has turned into a modern language that is more fun to use and with better defaults.

This book aims to give the reader a solid foundation to write efficient applications as well as an insight into strategies for implementing libraries in modern C++. We have tried to take a practical approach to explain how C++ works today, where C++14/C++17 features are a natural part of the language, rather than looking at C++ historically.

This book has been written by us, Viktor and Björn, collaboratively. However, the drafts of each chapter were written individually, and after that, we have worked together to improve the chapters and assemble them into a complete book. Viktor is the main author of chapter 1, 2, 5, 8, 9, and 11. Björn is the main author of chapter 3, 4, 7, and 10. We have worked hard to attain a consistent style throughout the book, and we think that it has been a big advantage to write this book together. Many subjects have been debated and processed for the better.
