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.

Essential Utilities

This chapter will introduce some essential classes from the C++ Utility library. Some of the metaprogramming techniques presented in the previous chapter will be used in order to work effectively with collections that contain elements of different types.

C++ containers are homogenous, meaning that they can only store elements of one single type. A std::vector<int> stores a collection of integers and all objects stored in a std::list<Boat> are of type Boat. But sometimes, we need to keep track of a collection of elements of different types. I will refer to these collections as heterogenous collections. In a heterogeneous collection, the elements may have different types. The following figure shows an example of a homogenous collection of ints and a heterogenous collection with elements of different types:

This chapter will cover a set of useful templates from the C++ Utility library...
