Functional programming is a style of programming that emphasizes the use of functions (in contrast to object-oriented programming, which emphasizes the use of objects). It has become popular in recent years because of its simplicity, conciseness, and clarity. This book teaches functional programming as a way of thinking and problem solving, using Haskell, the most popular purely functional language. Rather than using the conventional (boring) mathematical examples commonly found in other programming language textbooks, the author uses examples drawn from multimedia applications, including graphics, animation, and computer music, thus rewarding the reader with working programs for inherently more interesting applications. Aimed at both beginning and advanced programmers, this tutorial begins with a gentle introduction to functional programming and moves rapidly on to more advanced topics. Details about progamming in Haskell are presented in boxes throughout the text so they can be easily found and referred to.

A balance of flexible and inflexible qualities make Haskell a fascinating programming language to learn and use.First, the Haskell programming language is not named after Eddie Haskell, the sneaky double-dealing neighbor kid in the ancient TV sitcom, Leave It To Beaver.Haskell is named after Haskell Brooks Curry, an American mathematician and logician. If you don't know, logicians create models to describe and define human reasoning, for example, problems in mathematics, computer science, and philosophy. Haskell's main work was in combinatory logic, a notation designed to eliminate the need for variables in mathematical logic. Combinatory logic captures many key features of computation and, as a result, is useful in computer science. Haskell has three programming languages named after him: Haskell, Brooks, and Curry.Haskell the language is built around functions, useful blocks of code that do specific tasks. They are called and used only when needed.Another interesting feature of functional languages like Haskell: functions are treated as values like integers (numbers) and strings. You can add a function to another function the way you can add an integer to an integer, 1 + 1 or 35 + 53. Perhaps the best way to describe this quality is a spreadsheet: in a cell in the spreadsheet, you can add numbers as well as a combination of functions to work on numbers. For example, you might specify each number in cells 1-10 be added up as a sum. In Excel, at least, you also can use SUMIF to look for a pattern in cells 1-10 and, if the pattern is found, perform an action on any cells with the pattern.What Makes Haskell Special?Technically, Haskell is a general-purpose functional programming language with non-strict semantics and strong static typing. The primary control construct is the function. (Say that fast ten times!) Here's what it means: - Every language has a strategy to evaluate when to process the input arguments used in a call to a function. The simplest strategy is to evaluate the input arguments passed then run the function with the arguments. Non-strict semantics means the input arguments are not evaluated unless the arguments passed into the function are used to evaluate what is in the body of the function.- Programming languages have rules to assign properties - called a type - to the components of the language: variables, functions, expressions, and modules. A type is a general description of possible values the variable, function, expression, or module can store. Typing helps minimize bugs, for example, when a calculation uses a string ("house" or "cat") instead of a number (2 or 3). Strong static typing evaluates the code before runtime, when the code is static and possibly as code is written.- The order in which statements, instructions and functions are evaluated and executed determines the results of any piece of code. Control constructs define the order of evaluation. Constructs use an initial keyword to flag the type of control structure used. Initial keywords might be "if" or "do" or "loop" while final keywords might be "end if" or "enddo" or "end loop". Instead of a final keyword, Haskell uses indentation level (tabs) or curly brackets, or a mix, to indicate the end of a control structure.Perhaps what makes Haskell special is how coders have to think when they use the language. Functional programming languages work in very different ways than imperative languages where the coder manages many low-level details of what happens in their code and when. While it is true all languages have things in common, it's also true languages are mostly functional or mostly imperative, the way people are mostly right handed or left handed. Except functional programming languages require a different way of thinking about software as you code.

Introduction To Functional Programming Systems Using Haskell written by Antony J. T. Davie and has been published by Cambridge University Press this book supported file pdf, txt, epub, kindle and other format this book has been release on 1992-06-18 with Computers categories.

Here is an introduction to functional programming and its associated systems. A unique feature is its use of the language Haskell for teaching both the rudiments and the finer points of the functional technique. Haskell is a new, internationally agreed and accepted functional language that is designed for teaching, research and applications, that has a complete formal description, that is freely available, and that is based on ideas that have a wide consensus. Thus it encapsulates some of the main thrusts of functional programming itself, which is a style of programming designed to confront the software crisis directly. Programs written in functional languages can be built up from smaller parts, and they can also be proved correct, important when software has to be reliable. Moreover, a certain amount of parallelism can be extracted from functional languages automatically. This book serves as an introduction both to functional programming and Haskell, and will be most useful to students, teachers and researchers in either of these areas. An especially valuable feature are the chapters on programming and implementation, along with a large number of exercises.
