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.

Learning Modern Core Language Features

The C++ language has gone through a major transformation in the past decade with the development and release of C++11 and then, later, with its newer versions: C++14, C++17, and C++20. These new standards have introduced new concepts, simplified and extended existing syntax and semantics, and overall transformed the way we write code. C++11 looks like a new language, and code written using the new standards is called modern C++ code.

The recipes included in this chapter are as follows:

  • Using auto whenever possible
  • Creating type aliases and alias templates
  • Understanding uniform initialization
  • Understanding the various forms of non-static member initialization
  • Controlling and querying object alignment
  • Using scoped enumerations
  • Using override and final for virtual methods
  • Using range-based for loops to iterate on a range
  • Enabling range-based for loops for custom types
  • Using explicit constructors and conversion operators to avoid implicit conversion
  • Using unnamed namespaces instead of static globals
  • Using inline namespaces for symbol versioning
  • Using structured bindings to handle multi-return values
  • Simplifying code with class template argument deduction

Let's start by learning about automatic type deduction.
