Expression (computer science)

In computer science, an expression is a syntactic entity in a programming language that may be evaluated to determine its value of a specific semantic type. It is a combination of one or more constants, variables, functions, and operators that the programming language interprets (according to its particular rules of precedence and of association) and computes to produce ("to return", in a stateful environment) another value.
