C++17 STL Cookbook

By: Jacek Galowicz

Overview of this book

C++ has come a long way and is in use in every area of the industry. Fast, efficient, and flexible, it is used to solve many problems. The upcoming version of C++ will see programmers change the way they code. If you want to grasp the practical usefulness of the C++17 STL in order to write smarter, fully portable code, then this book is for you. Beginning with new language features, this book will help you understand the language’s mechanics and library features, and offers insight into how they work. Unlike other books, ours takes an implementation-specific, problem-solution approach that will help you quickly overcome hurdles. You will learn the core STL concepts, such as containers, algorithms, utility classes, lambda expressions, iterators, and more, while working on practical real-world recipes. These recipes will help you get the most from the STL and show you how to program in a better way. By the end of the book, you will be up to date with the latest C++17 features and save time and effort while solving tasks elegantly using the STL.

Building your own zip iterator adapter

Different programming languages lead to different programming styles. This is, because there are different ways to express things, and they are differing in their elegance for each use case. That is no surprise because every language was designed with specific objectives.

A very special kind of programming style is purelyfunctional programming. It is magically different from the imperative programming which C or C++ programmers are used to. While this style is very different, it enables extremely elegant code in many situations.

One example of this elegance is the implementation of formulas, such as the mathematical dot product. Given two mathematical vectors, applying the dot product to them means pairwise multiplying of the numbers at the same positions in the vector and then summing up all of those multiplied values. The dot product of two vectors (a, b, c) * (d, e, f) is (a * e + b * e + c * f). Of course, we can do that with C and C++, too. It could...
