A class must be constructed so it must have a constructor right? A constructor would only be relevant to the class it is in and would not work for derived classes correct? The compiler must know what object is being constructed so you have to use the object name when constructing it right? A class must be constructed so the constructor must be called automatically correct? So they are all true correct?
