the latter.

Yep

Not if there are other constructors.

It would be non-standard.

Nope.  It's just that you must explicitly initialize the base class in
the constructors of the derived class, when the base class offers no
default constructor.

If you have further questions about the C++ language, please use a
more appropriate forum.  This mailing list is about the development
of GCC, not about learning C++ with GCC.
