Imperative programming

In computer science, imperative programming is a programming paradigm.

Description

The imperative programming paradigm describes computation in terms of statements that change a program state.

In much the same way that the imperative mood in natural languages expresses commands to take action, imperative programs define sequences of commands for the computer to perform.

Imperative programming (necessary programming) is focused on describing how a program operates.

Declarative programming

The term is often used in contrast to declarative programming, which focuses on what the program should accomplish without prescribing how to do it in terms of sequences of actions to be taken.

Analogy: curriculum and syllabus
