Modern C++ Programming Cookbook

Overview of this book

C++ is one of the most widely used programming languages. Fast, efficient, and flexible, it is used to solve many problems. The latest versions of C++ have seen programmers change the way they code, giving up on the old-fashioned C-style programming and adopting modern C++ instead. Beginning with the modern language features, each recipe addresses a specific problem, with a discussion that explains the solution and offers insight into how it works. You will learn major concepts about the core programming language as well as common tasks faced while building a wide variety of software. You will learn about concepts such as concurrency, performance, meta-programming, lambda expressions, regular expressions, testing, and many more in the form of recipes. These recipes will ensure you can make your applications robust and fast. By the end of the book, you will understand the newer aspects of C++11/14/17 and will be able to overcome tasks that are time-consuming or would break your stride while developing.

Preface

Using atomic types


The thread library provides support for managing threads and synchronizing access to shared data with mutex and locks. The standard library provides support for the complementary, lower-level atomic operations on data, that is, indivisible operations that can be executed concurrently from different threads on shared data without the risk of producing race conditions and without the use of locks. The support it provides includes atomic types, atomic operations, and memory synchronization ordering. In this recipe, we will see how to use some of these types and functions.

Getting ready

All the atomic types and operations are defined in the std namespace in the <atomic> header. 

How to do it...

The following is a series of typical operations that use atomic types:

  • Use the std::atomic class template to create atomic objects that support atomic operations, such as loading, storing, or performing arithmetic or bitwise operations:
        std::atomic<int> counter {0};
