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.

The future of the Ranges library

The Ranges library that got accepted in C++20 was based on a library authored by Eric Niebler, and is available at https://github.com/ericniebler/range-v3. Only a small subset of the components of this library have made their way into the standard at present, but more things are likely to be added soon.

In addition to many useful views that haven't been accepted yet, such as group_by, zip, slice, and unique, there is the concept of actions that can be piped in the same way that views can. However, instead of being lazy evaluated like views, actions perform eager mutations of ranges. Sorting is an example of a typical action.

If you cannot wait for these features to be added to the standard library, I recommend that you take a look at the range-v3 library.
