Hands-On Functional Programming with C++: An effective guide to writing accelerated functional code using C++17 and C++20 (English Edition)

Learn functional programming and build robust applications using the latest functional features in C++

Key Features

Learn programming concepts such as loops, expressive code, and simple parallelization

Understand the working of Lambdas and Currying and write Pure functions

Explore event sourcing and other functional patterns to improve the efficiency of your applications

Book Description

Functional programming enables you to divide your software into smaller, reusable components that are easy to write, debug, and maintain. Combined with the power of C++, you can develop scalable and functional applications for modern software requirements. This book will help you discover the functional features in C++ 17 and C++ 20 to build enterprise-level applications.

Starting with the fundamental building blocks of functional programming and how to use them in C++, you’ll explore functions, currying, and lambdas. As you advance, you’ll learn how to improve cohesion and delve into test-driven development, which will enable you in designing better software. In addition to this, the book covers architectural patterns such as event sourcing to help you get to grips with the importance of immutability for data storage. You’ll even understand how to “think in functions” and implement design patterns in a functional way.

By the end of this book, you’ll be able to write faster and cleaner production code in C++ with the help of functional programming.
