<P>
The <tt>SortedListAsArray</tt> class is declared in Program <A HREF="page189.html#progsorted2h" tppabs="http://dictator.uwaterloo.ca/Bruno.Preiss/books/opus4/html/page189.html#progsorted2h"><IMG ALIGN=BOTTOM ALT="gif" SRC="cross_ref_motif.gif" tppabs="http://dictator.uwaterloo.ca/Bruno.Preiss/books/opus4/icons/cross_ref_motif.gif"></A>.
Notice the use of multiple inheritance:
The <tt>SortedListAsArray</tt> class is derived from both
the <tt>SortedList</tt> class and the <tt>ListAsArray</tt> class.
The <tt>SortedList</tt> base class is an abstract class.
It provides the sorted list <em>interface</em>.
The <tt>ListAsArray</tt> base class is a concrete class
from which the sorted list class <em>inherits</em> much of its functionality.

<STRONG>Program:</STRONG> <tt>SortedListAsArray</tt> Class Definition<BR>
<P>
<P>
There are no addition member variables required to implement
the <tt>SortedListAsArray</tt> class.
I.e., the member variables provided by the base class
<tt>ListAsArray</tt> are sufficient.
However, there is an additional private member function declared
called <tt>FindOffset</tt>.
As explained below,
<tt>FindOffset</tt> is used by other member functions
to locate an item in the sorted list.
