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.

Robustness and Performance

C++ is often the first choice when it comes to selecting an object-oriented programming language with performance and flexibility as key goals. Modern C++ provides language and library features, such as rvalue references, move semantics, and smart pointers.

When combined with good practices for exception handling, constant correctness, type-safe conversions, resource allocation, and releasing, C++ enables developers to write better, more robust, and performant code. This chapter's recipes address all of these essential topics.

This chapter includes the following recipes:

  • Using exceptions for error handling
  • Using noexcept for functions that do not throw exceptions
  • Ensuring constant correctness for a program
  • Creating compile-time constant expressions
  • Creating immediate functions
  • Performing correct type casts
  • Using unique_ptr to uniquely own a memory resource
  • Using shared_ptr to share...
