With the current C++23 standard, C++ has many libraries to offer. My book's key idea is to give you concise the necessary information for all C++ standard libraries."The C++ Standard Library" provides a detailed overview of the C++ Standard Library, including C++23.

The Goal

The C++ Standard Library aims to provide you with a concise reference of the C++ standard library in about 350 pages. This book assumes that you are familiar with C++. If so, you will get the most benefit from this book. If C++ is new to you, you should start with a textbook about core C++. Once you have mastered a textbook about the core language, you can make your next big step by reading my book.

C++23 improved the big four of C++20: extended ranges functionality, the coroutine generator std::generator, and a modularized C++ standard library.The Standard Template Library (STL) consists of three components from a bird’s-eye view. Those are containers, algorithms that run on the containers, and iterators that connect both of them. The containers have only minimal requirements for their elements. This abstraction of generic programming enables you to combine algorithms and containers uniquely. The C++ Standard Library has a rich collection of containers. We have sequence and associative containers. Associative containers can be classified as ordered or unordered associative containers.

This book also has more than 100 running code examples for the code snippets I present. Therefore, you can combine theory with practice and get the most out of it.
