I picked this up because I needed to work with a c++ codebase. I picked up some good tricks while I was working my way through the codebase that I needed to update. I highly recommend this resource for c++ developers who want to learn some new tricks and maybe even refresh themselves with modern techniques in c++.

From the Publisher
What’s changed in C++ since the last edition of this book came out, and what’s changed in the book to help developers work with those changes?
The second edition of the book was published in late 2020. Since then, a new version of the standard has been developed. Although it will only be finally published in 2024, this version is known as C++23. Perhaps not a version as large as C++20, C++23 still offers a multitude of improvements and new features, both for the language and the standard library. In the new edition, readers can look forward to learning about span buffers, the stack trace library, the std::mdspan type, the std::expected type, and the multidimensional subscript operator. All of these and more are covered across 15 new and updated recipes. With a total of 23 new recipes and other improved ones, this edition explores the latest version of the standard but also includes more C++20 topics not previously covered.
C++ programming is a very broad subject, how did you decide which topics to cover and what to leave out?
Indeed, C++ is a multi-paradigm programming language with many features. It comes with a standard library that allows developers to use out-of-the box utilities (without resorting to third-party libraries or reinventing the wheel). The selection of topics was made to include all the important areas that developers come across, such as handling of strings and numeric types, lambdas and function templates, compilation, containers, algorithms, iterators, files and streams, time and dates, threads and synchronization mechanisms, and many other topics. Moreover, I also included a selection of patterns and idioms, as well as several unit testing frameworks to help developers learn not only how to write code but also how to ensure it does the right thing.
What was your aim when creating this book, and what will readers be able to do once they’ve read it?
When I started with this book 7 years ago, I wanted to present a different approach to teaching C++, with an emphasis on the new, modern way of using the language. I wanted it to be simple to read but to cover a broad range of topics of varying complexity, both for beginners and more experienced C++ programmers. With the second and third edition, the focus was on covering the new, at the time, C++20 and C++23 standards, respectively.
After finishing this book, readers will be able to master the language in all its areas and write high-quality C++ code. Moreover, in the third edition, I am particularly excited to share the recipes covering std::expected, std::mdspan, and std::optional types in chapter 6, as well as several new ones covering the ranges library from chapter 12.
How does your book stand out from all the other C++ books out there?
The idea of a cookbook is to present developers with recipes that propose solutions to challenges that they regularly face. This book is a collection of over 150 such recipes that cover a multitude of topics and solutions using language and library features from C++11/14/17/20/23. The updates in the second and the third edition are focused on the C++20 and C++23 standards, respectively. Developers can not only use the book as a reference to many of the modern C++ language and library features but also as a guide to solving various programming tasks.
