Summary of Class Presentation for March 29, 1999

	Due to continuing instructor illness, class interaction was limited.
We did examine today's sample programs, however.  Students should 
particularly notice the following items:
1.  an object can contain objects of its own or other classes;
2.  those object must have their constructors called explicitly in the
header of the constructor for the containing object.  After the parameter
list, a : is put followed by the constructor calls for those objects 
with parameters.  These parameters must be from the parameter list of the
encompassing object.  The constructor calls are separated by commas and 
followed by the opening { of the enclosing constructor.

	The differences between member functions and other functions 
were described for review.  There are three major ones:
1.  member functions are included in a class for use by its objects;
2.  member functions may be private or public
3.  member functions can directly access the variables of the object and
its class.
4.  member functions are called with a different syntax than that used 
for calling regular functions.  IN particular, a member function call must
start with an object-name.function-name.

	Students were presented with three alternatives for how the last
several weeks of the class could be done.  The instructor is concerned 
that many students seem not to be competent programmers.  Since programming
is a vital skill for a successful start to an MIS career, the instructor
wants to do whatever he can to help students acquire this skill.  Students
will vote on the three alternatives at the next class meeting.
