What Is an Expression in Programming?

An expression in programming is a combination of values, variables, operators, and function calls that are evaluated to produce a single value. Expressions are a fundamental building block in most programming languages and are used to perform computations, assign values, and control logic.

In simple terms, an expression is any piece of code that can be evaluated to produce a single value. This value can be a number, string, boolean, or any other data type supported by the programming language.

Expressions are used to compute results, manipulate data, and control program flow.
