Which term best matches the definition 'A piece of code that has a value, such as 3 + 5'?

• A. Data
• B. Expression
• C. Float
• D. Function

Answer: (B)

An expression is a piece of code that can be evaluated to produce a value. In the example 3 + 5, you have two numbers and an operator; evaluating it yields the numeric value 8. That ability to compute and return a value is what makes it an expression. Data is just a value itself (like 3 or 5) and a float is a type for numbers with decimals. A function is a named block of code that performs actions and can return a value when called, but it’s not the computed value itself. So the term that best fits a piece of code that has a value is expression.
