They have no special semantics.

There is no such operator.  There is a member function c_str which tacks a
NUL onto the end of the array and returns it.  It does not look inside the
array to see if there are any already there.

No.

No.

There is no proper substring class; there is a substring method which
returns a new string copied from the old one.  I imagine that a string
class which provides substring management will be a popular derivation.
