Key FeaturesModularize your applications and make them highly reusable and testableGet familiar with complex concepts such as metaprogramming, concurrency, and immutabilityA highly practical guide to building functional code in C++ filled with lots of examples and real-world use casesBook DescriptionFunctional programming allows developers to divide programs into smaller, reusable components that ease the creation, testing, and maintenance of software as a whole. Combined with the power of C++, you can develop robust and scalable applications that fulfill modern day software requirements. This book will help you discover all the C++ 17 features that can be applied to build software in a functional way.The book is divided into three modules—the first introduces the fundamentals of functional programming and how it is supported by modern C++. The second module explains how to efficiently implement C++ features such as pure functions and immutable states to build robust applications. The last module describes how to achieve concurrency and apply design patterns to enhance your applications performance. Here, you will also learn to optimize code using metaprogramming in a functional way.By the end of the book, you will be familiar with the functional approach of programming and will be able to use these techniques on a daily basis.What you will learnGet to know the difference between imperative and functional approachesSee the use of first-class functions and pure functions in a functional styleDiscover various techniques to apply immutable state to avoid side effectsDesign a recursive algorithm effectivelyCreate faster programs using lazy evaluationStructure code using design patterns to make the design process easierUse concurrency techniques to develop responsive softwareLearn how to use the C++ Standard Template Library and metaprogramming in a functional way to improve code optimizationAbout the AuthorWisnu Anggoro is a Microsoft Certified Professional in C# programming and an experienced C/C++ developer. He has also authored the books Boost.Asio C++ Network Programming - Second Edition and Functional C# by Packt. He has been programming since he was in junior high school, which was about 20 years ago, and started developing computer applications using the BASIC programming language in the MS-DOS environment. He has solid experience in smart card programming, as well as desktop and web application programming, including designing, developing, and supporting the use of applications for SIM Card Operating System Porting, personalization, PC/SC communication, and other smart card applications that require the use of C# and C/C++. He is currently a senior smart card software engineer at CIPTA, an Indonesian company that specializes in innovation and technology for smart cards.
