You cannot declare an array of class objects using other than the default
(no parameters) constructor.  There is no syntax to support it.  You can
declare a constructor with all default parameters standing in for the
default constructor, and that one will be used.  That's the best you can do.
(This last is a language change, and works with recent C++ compilers.)
