Question

help on C++ anyone?

Answer 1

What is the question?

Answer 2

It is declaring the method. So, it is the header (I believe).

A call would not have defining these as returning specific type.

Prototype would have the method's code as well.

Answer 3

Let me ask what class you are taking?

Answer 4

You declare functions/methods as:
type name(arguments);

You invoke / call functions as:
name(value);

You prototype functions/methods as:
type name(arguments) {
do x, y and z;
return value of type;
}
