Overview of this book

C++ has come a long way to be one of the most widely used general-purpose languages that is fast, efficient, and high-performance at its core. The updated second edition of Modern C++ Programming Cookbook addresses the latest features of C++20, such as modules, concepts, coroutines, and the many additions to the standard library, including ranges and text formatting. The book is organized in the form of practical recipes covering a wide range of problems faced by modern developers. The book also delves into the details of all the core concepts in modern C++ programming, such as functions and classes, iterators and algorithms, streams and the file system, threading and concurrency, smart pointers and move semantics, and many others. It goes into the performance aspects of programming in depth, teaching developers how to write fast and lean code with the help of best practices. Furthermore, the book explores useful patterns and delves into the implementation of many idioms, including pimpl, named parameter, and attorney-client, teaching techniques such as avoiding repetition with the factory pattern. There is also a chapter dedicated to unit testing, where you are introduced to three of the most widely used libraries for C++: Boost.Test, Google Test, and Catch2. By the end of the book, you will be able to effectively leverage the features and techniques of C++11/14/17/20 programming to enhance the performance, scalability, and efficiency of your applications.

Understanding module partitions

The source code of a module may become large and difficult to maintain. Moreover, a module may be composed of logically separate parts. To help with scenarios such as these, modules support composition from parts called partitions. A module unit that is a partition that exports entities is called a module interface partition.

However, there could also be internal partitions that do not export anything. Such a partition unit is called a module implementation partition. In this recipe, you will learn how to work with interface and implementation partitions.

Getting ready

You should read the previous recipe, Working with modules, before continuing with this one. You will need both the module fundamentals we discussed there and the code examples that we will continue with in this recipe.

How to do it...

You can split a module into several partitions as follows:

  • Each partition unit must start with a statement of the form export...
