Question

Look at the following function prototype.

int myFunction(double);

What is the data type of the function's return value?
A) int
B) double
C) void
D) Can't tell from the prototype

Answer 1

The data type of the function's return value in the prototype int myFunction(double); is of type int. It is specified before the function's name in the prototype, indicating what type of value the function will return.

Step-by-step explanation:

The function prototype provided is int myFunction(double);. The data type of the function's return value is specified first in the prototype. In this case, the return value is of type int. This means when the function completes its execution, it will return an integer value to where it was called from.

The portion inside the parentheses, (double), indicates that the function takes a single argument of type double, which is a floating-point number. However, the argument's type does not affect the return type of the function.

Therefore, the correct answer to the question is A) int as it is the type that appears before the function name, indicating the function's return type.
