C++17 STL Cookbook

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.

Introduction


This chapter is devoted to string handling, parsing, and printing of arbitrary data. For such jobs, STL provides its I/O stream library. The library basically consists of the following classes, which are each depicted in gray boxes:

The arrows show the inheritance scheme of the classes. This might look very overwhelming at first, but we will get to use most of these classes in this chapter and get familiar with them class by class. When looking at those classes in the C++ STL documentation, we will not find them directly with these exact names. That is because the names in the diagram are what we see as application programmers, but they are really mostly just typedefs of classes with a basic_ class name prefix (for example, we will have an easier job searching the STL documentation for basic_istream rather than istream). The basic_* I/O stream classes are templates that can be specialized for different character types. The classes in the diagram are specialized on char values...
