Question

If a function doesn’t return a value, the word _________ will appear as its return type.

Short answer

#Answer# The return type of a function that doesn't return any value is "void".

Step-by-step solution

Introduction

To find the right word to fill in the blank, we need to understand what is a "return type" of a function and what it means for a function not to return a value.

Return Type

In most programming languages, a function often has a return type, which refers to the type of value that it returns (e.g., integer, float, string). The return type is usually specified in the function's definition.

Functions with No Return Value

Some functions do not return a value; their main purpose is to perform actions or side effects. In this case, a different return type is needed to indicate that no value is returned.

The Answer

The correct word to fill in the blank is "void". If a function doesn't return a value, the word "void" will appear as its return type. This is a convention used in many programming languages (e.g., C, C++, Java) to denote a function that performs an action and doesn't return any value.
