Introduction and Definitions Most programming languages describe computation in an imperative style. Some definitions from Wikipedia: Imperative Programming Imperative programs define sequences of commands for the computer to perform. A programming paradigm that describes computation in terms of statements that change a program state Declarative programming Declarative programs express what the program
