Question

Is a call to a void function used as a statement or is it used as an expression?

Short answer

Answer: A call to a void function is considered a statement, as it performs an action without returning any value.

Step-by-step solution

Define a statement

A statement is a piece of code that performs an action but does not return a value. Statements are often used to control the flow of a program and are typically executed one after another in a code block.

Define an expression

An expression is a combination of values, variables, operators, and function calls that are evaluated to produce a single value. Expressions can be used as part of a larger statement, such as an assignment statement or a function call, and their results can be stored in variables or used in calculations.

Analyze a void function call

A void function call is a call to a function that does not return any value. Void functions are typically used to perform specific tasks or modify the state of a program without necessarily producing a result that needs to be stored or used in further calculations.

Determine if a void function call is a statement or an expression

Since a void function call does not return any value and primarily performs an action, it is considered to be a statement rather than an expression. It can be used to control the flow of a program or perform specific tasks, fulfilling the definition of a statement.
