This is a red herring, because in C++ a struct is a kind of class.

Only classes can inherit from each other.  Two interesting examples of
classes (as defined in the Standard) are structs and unions.

The confusion may have come about because enums also follow some of the
same rules as the other types of classes.  However, they aren't classes.

You must have been reading about some other language.
It is not possible in C++.

Hi Steve !
What you wrote above is not completely true. Not only a class
but also structures can inherit from each other.
( I don't know what happens if a class inherits from a structure
or vice versa ...)

Bye,

A class is a struct, and a struct is a class. The ONLY difference is
the default access. You can even write

 class A; // forward declarations
 struct B;
 ...
 // definitions:
 struct A { ... };
 class B { ... };

No. Only a class may inherit, and then only from another class.

A derived class inherits the enums of its base classes, of course.

I had read somewhere that it is possible for an enum to inherit
from another enum. If this is so what is the syntax? I have tried
various forms to no avail. Then again who knows what my compiler
would make of it anyhow.
any reply would be appreciated,
