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.

Preprocessing and Compilation

In C++, compilation is the process by which source code is transformed to machine code and organized in object files that are then linked together to produce an executable. The compiler actually works on a single file at a time, produced by the preprocessor (the part of the compiler that handles preprocessing directives) from a single source file and all the header files that it includes. This is, however, an oversimplification of what happens when we compile the code. This chapter addresses topics related to preprocessing and compilation, with a focus on various methods to perform conditional compilation, but also touching other modern topics such as using attributes to provide implementation-defined language extensions.

The recipes included in this chapter are as follows:

  • Conditionally compiling your source code
  • Using the indirection pattern for preprocessor stringification and concatenation
  • Performing compile-time assertion...
