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 Numbers and Strings

Numbers and strings are the fundamental types of any programming language; all other types are based on or composed of these ones. Developers are confronted all the time with tasks such as converting between numbers and strings, parsing and formatting strings, and generating random numbers. This chapter is focused on providing useful recipes for these common tasks using modern C++ language and library features.

The recipes included in this chapter are as follows:

  • Converting between numeric and string types
  • Limits and other properties of numeric types
  • Generating pseudo-random numbers
  • Initializing all the bits of the internal state of a pseudo-random number generator
  • Creating cooked user-defined literals
  • Creating raw, user-defined literals
  • Using raw string literals to avoid escaping characters
  • Creating a library of string helpers
  • Verifying the format of a string using regular...
