In computer science, a local variable is a variable that is given local scope. Such variables are accessible only from the function or block in which it is declared. Wikibooks has more about this subject: Wikiversity Riverside Graphics Lab Open Directory Project: Computer Science Collection of Computer Science Bibliographies Belief that title science in computer science is inappropriate Categories: Computer science | Academic disciplines ... In computer science and mathematics, a variable is a symbol denoting a quantity or symbolic representation. ... This article is about the use of the term in computer science. ... In computer science, a subroutine (function, procedure, or subprogram) is a sequence of code which performs a specific task, as part of a larger program, and is grouped as one, or more, statement blocks; such code is sometimes collected into software libraries. ...

Local variables are special because in most languages they are stored on the function stack directly. This means that when a recursive function calls itself, local variables in each instance of the function are given separate memory address space. Hence variables of this scope can be declared, written to, and read, without any risk of side-effects. In mathematical logic and computer science, the recursive functions are a class of functions from natural numbers to natural numbers which are computable in some intuitive sense. ... In computing, an address space defines a context in which an address makes sense. ... In computer science, a side-effect is a property of a programming language function that it modifies some state other than its return value. ...

Some programming paradigms and languages, such as functional programming (and its languages such as Haskell) require all variables to be of local scope, and the functionality of the program is achieved only by passing local variables from one function to another. Functional programming is a programming paradigm that treats computation as the evaluation of mathematical functions. ...
