Functional Programming In C

Functional C teaches how to program in C, assuming that the student has already learnt how to formulate algorithms in a functional style. By using this as a starting point, the student will become a better C programmer, capable of writing programs that are easier to comprehend, maintain and that avoid common errors and pitfalls. All program code that appears in Functional C is available on our ftp server - see below. How to find a code fragment? To access a particular code fragment, use the book to locate the section or subsection in which the code fragment appears, then click on that section in the code index . This will open the appropriate page at the beginning of the section. The code fragment may then be selected using the copy/paste facilities of your browser. Each chapter is represented by a separate page, so as an alternative to the procedure above you can use the save-as menu of your browser to up-load all code fragments in a particular chapter at once. Also available on our ftp server is errata for Functional C.

Functional Programming in C#, Second Edition teaches functional thinking for real-world problems. It reviews the C# language features that allow you to program functionally and through many practical examples shows the power of function composition, data-driven programming, and immutable data structures. All code examples work with .NET 6 and C# 10.

Functional programming languages like F#, Erlang, and Scala are attractingattention as an efficient way to handle the new requirements for programmingmulti-processor and high-availability applications. Microsoft's new F# is a truefunctional language and C# uses functional language features for LINQ andother recent advances. Real-World Functional Programming is a unique tutorial that explores thefunctional programming model through the F# and C# languages. The clearlypresented ideas and examples teach readers how functional programming differsfrom other approaches. It explains how ideas look in F#-a functionallanguage-as well as how they can be successfully used to solve programmingproblems in C#. Readers build on what they know about .NET and learn wherea functional approach makes the most sense and how to apply it effectively inthose cases. The reader should have a good working knowledge of C#. No prior exposure toF# or functional programming is required. Purchase of the print book comes with an offer of a free PDF, ePub, and Kindle eBook from Manning. Also available is all code from the book.

Learn functional programming and build robust applications using the latest functional features in C++ Key FeaturesLearn programming concepts such as loops, expressive code, and simple parallelizationUnderstand the working of Lambdas and Currying and write Pure functionsExplore event sourcing and other functional patterns to improve the efficiency of your applicationsBook 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. What you will learnUnderstand the fundamentals of functional programmingStructure your code by understanding the building blocks of functional programmingCompare design styles in functional programming and object-oriented programming (OOP)Use the concept of currying to create new functions in C++Become skilled at implementing design patterns in a functional wayGet to grips with multithreading by means of functional programmingLearn how to improve memory consumption when using functional constructsWho this book is for This book is for C++ developers who want to learn functional programming but have little to no knowledge of the paradigm. Although no prior knowledge of functional programming is necessary, basic C++ programming experience will help you understand key concepts covered in the book.

An Essential Reference for Intermediate and Advanced R Programmers Advanced R presents useful tools and techniques for attacking many types of R programming problems, helping you avoid mistakes and dead ends. With more than ten years of experience programming in R, the author illustrates the elegance, beauty, and flexibility at the heart of R. The book develops the necessary skills to produce quality code that can be used in a variety of circumstances. You will learn: The fundamentals of R, including standard data types and functions Functional programming as a useful framework for solving wide classes of problems The positives and negatives of metaprogramming How to write fast, memory-efficient code This book not only helps current R users become R programmers but also shows existing programmers what’s special about R. Intermediate R programmers can dive deeper into R and learn new strategies for solving diverse problems while programmers from other languages can learn the details of R and understand why R works the way it does.
