1.16) Is A Class An Object? (Object-Oriented Technology)

In C++ no, because C++ classes are not instances of an accessible class (a
Meta-Class) and because C++ classes are not accessible to programs. Classes
are objects in 3 Level Systems and above because classes are instances of
meta-classes. But classes play a dual role, because objects can only be
declared to be instances of a class (and class objects instances of a
meta-class). In 1 Level (single-hierarchy) systems, all classes are objects.
