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.

Summary

This chapter presented a number of motivations behind using Range views to construct algorithms. By using views, we can compose algorithms efficiently, and with a succinct syntax, using the pipe operator. You also learned what it means for a class to be a view and how to use range adaptors that turn ranges into views.

A view does not own its elements. Constructing a range view is required to be a constant time operation and all views are evaluated lazily. You have seen examples of how we can convert a container into a view, and how to materialize a view back into an owning container.

Finally, we covered a brief overview of the views that come with the standard library, and the likely future of ranges in C++.

This chapter is the last in the series about containers, iterators, algorithms, and ranges. We will now move on to memory management in C++.
