what ever data members,member functions present in super class are applicable to subclass...subclass may contain more additional features....so its obvious that size of subclass object is more than superclass object...now lets take an analogy of float(4 bytes) and double( 8 bytes) float can be implicitly converted into double( as float size is less when compared to double) but not vice versa....then why is this not applicable to superclass object and subclass object(as size of superclass object is less when compared to subclass)? please tell if am wrong!
