Modern C++ Programming Cookbook - Second Edition

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 Files and Streams

One of the most important parts of the C++ standard library is the input/output (I/O), stream-based library that enables developers to work with files, memory streams, or other types of I/O devices. The first part of this chapter provides solutions to some common stream operations, such as reading and writing data, localization settings, and manipulating the input and output of a stream. The second part of the chapter explores the new C++17 filesystem library that enables developers to perform operations with the filesystem and its objects, such as files and directories.

The recipes covered in this chapter are as follows:

  • Reading and writing raw data from/to binary files
  • Reading and writing objects from/to binary files
  • Using localized settings for streams
  • Using I/O manipulators to control the output of a stream
  • Using monetary I/O manipulators
  • Using time I/O manipulators
  • Working with filesystem paths
