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.

Working with modules

Modules are one of the most important changes in the C++20 standard. They represent a fundamental change to the C++ language and the way we write and consume code. Modules are made available in source files that are compiled separately from the translation units that consume them.

Modules provide multiple advantages, especially in comparison to the use of header files.

  • They are only imported once and the order they're imported in does not matter.
  • They do not require splitting interfaces and implementation in different source files, although this is still possible.
  • Modules have the potential of reducing compilation time, in some cases significantly. The entities exported from a module are described in a binary file that the compiler can process faster than traditional precompiled headers.
  • Moreover, this file can potentially be used to build integrations and interop with C++ code from other languages.
