Final answer:
The true statement for a void function is E) A and D, as such functions do not return any value, but they can contain a return statement to exit the function prematurely.
Step-by-step explanation:
When discussing functions in programming, particularly in languages like C, C++, or Java, it's essential to understand the behavior of different types of functions. A void function is a type of function that does not return a value to the caller. Instead, void functions are used to perform an action or a series of actions without the need to send a value back to the function's caller.
Let's address the provided options to determine which one is true for a void function:
A) There cannot be a return statement. This is not entirely true. A void function can have a return statement, but it does not return a value. Instead, it is used to exit the function prematurely.
B) The value of 0 should be returned. This is incorrect because a void function does not return any value, including 0.
C) The value of void should be returned. This is not possible as 'void' is not a value that can be returned. It represents the absence of any value.
D) Nothing is returned. This is correct. By definition, a void function does not return a value upon completion.
Considering the clarification above, the correct option that is true for a void function is D) Nothing is returned. This aligns with the definition and usage of void functions in programming. The claim that there cannot be a return statement is a common misconception; the presence of a return statement is allowed as long as it doesn't attempt to return a value. Hence, the final answer, considering all the points, is E) A and D.
