Summary of Class Presentation of March 24, 1999

	We continued to examine simple examples of object-oriented C++
code.  In particular, we looked at using the default parameter and at`
overriding the default paramters of a constructor and at a simple 
destructor.  
  	The items you should be familiar with from today include:
1.  multiple objects of a single class
2.  using the parameters of a constructor
3.  the purpose of a destructor
4.  how to write a destructor
5.  for automatically created objects, the order in which constructors
and destructors are invoked.
	We also did an in-class exercise which asked students to modify 
one of the programs discussed today to provide an additional feature.
