  2. Imperative programming - Wikipedia

    In computer science, imperative programming is a programming paradigm that uses statements that change a program's state. In much the same way that the imperative mood in natural languages expresses commands, an imperative program consists of commands for the computer to perform. Imperative programming focuses on describing how a program operates.

  3. Programming language - Simple English Wikipedia, the free ...

    Imperative programming languages describe a system of state changes. At the start, the program is in a certain state, and the computer is given steps to follow, in order to perform an action. Following the steps causes the program to "change state". In general, declarative programming languages are safer and shorter.

  4. Imperative - Wikipedia

    Imperative may refer to: Imperative mood, a grammatical mood (or mode) expressing commands, direct requests, and prohibitions. Imperative programming, a programming paradigm in computer science. Imperative logic.

  5. Declarative programming - Wikipedia

    Declarative programming is a non-imperative style of programming in which programs describe their desired results without explicitly listing commands or steps that must be performed. Functional and logical programming languages are characterized by a declarative programming style. In logical programming languages,...

  6. Imperative programming - McGill School Of Computer Science

    In computer science, imperative programming, as contrasted with declarative programming, is a programming paradigm that describes computation as statements that change a program state. In much the same way as the imperative mood in natural languages expresses commands to take action, imperative programs are a sequence of commands for the computer to perform.

  7. Functional programming - Wikipedia

    In computer science, functional programming is a programming paradigm—a style of building the structure and elements of computer programs—that treats computation as the evaluation of mathematical functions and avoids changing-state and mutable data. It is a declarative programming paradigm in that programming is done with expressions or declarations instead of statements. In functional code, the output value of a function depends only on its arguments, so calling a function with the same ...

  8. List of programming languages by type - Wikipedia

    Declarative programming stands in contrast to imperative programming via imperative programming languages, where control flow is specified by serial orders (imperatives). (Pure) functional and logic-based programming languages are also declarative, and constitute the major subcategories of the declarative category.

  9. Procedural programming - Wikipedia

    Imperative programming. Procedural programming languages are also imperative languages, because they make explicit references to the state of the execution environment. This could be anything from variables (which may correspond to processor registers) to something like the position of the "turtle" in the Logo programming language . Often,...

  10. Programming language - Wikipedia

    A programming language is a notation for writing programs, which are specifications of a computation or algorithm. Some authors restrict the term "programming language" to those languages that can express all possible algorithms. Traits often considered important for what constitutes a programming language include: Function and target
