Week 04 Notes for CS 1500 -- Spring 2000
(this is draft material)

* Take roll

* All future assignments will include directions
  for subject lines for e-mail messages.  Please
  be sure to use the exact subject line
  specified.  Otherwise, sorting e-mail becomes
  an onerous task.

* Take a look at new lab assignment

* Take a look at quiz day scheduled.

* Announce that class grades have been posted in
  the class web space, keyed by last four digits
  of student id number.

* What was the most frequent error in the lab
  program?  Other problems with how lab was done?
  Problems with how first solo program was done?

* Warning: Last day to turn in solo #1 late is
  Sunday, March 12.  There is a 10% penalty per
  calendar day late.  Each 10% is worth a full
  letter grade.

* Take a look at minor change Solo1 assignment
  document: if you have not already turned in
  the program, please use the subjects now
  specified there.

* Finish up with some stuff from last week: how
  the value of an expression depends on operator
  precedence.

* Lecture topic: EXAMPLE OF A PROGRAM THAT USES
                 FUNCTIONS (see the esample
		 below.)

* Lecture topic: IMPORTANCE OF PRE- AND
                 POST-CONDITIONS
  - Shiflet uses the example of f=abs(x)
  - consider the value of pre- and
    post-conditions to you as the user of a
    function such as "cp"
  - then consider that the people who use the
    programs you write will be in the same
    position.

* Lecture topic: IMPLEMENTATION OF FUNCTION
                 CALLS (c.f. pp. 855-856)
  - This helps explain the effect of a function
    call
    + how value parameters are passed
    + why an expression can be used as an
      actual parameter
    + understanding the scope of a local
      variable.
    + understanding that a called function
      cannot change the callers copy of a
      parameter passed by value.
    + global variables are special: visible
      everywhere except where they are "masked."

    
* Lecture topic: ADT's AND CLASSES: WHAT ARE
		 THEY AND WHAT ARE THEY GOOD FOR?

FRIDAY
==================================================

* Info about quiz form and questions:  There is
  a new document in the class web space that
  gives you some information on how to study for
  the quiz.  Have a look -- click on
  "studyGuide" at the bottom of the list.

* Something to remember about the lab today:
  Refer to the directions in the text and the
  online directions.  Follow all directions
  exactly.  If you have questions, ask.  Test
  your program carefully and check its answers
  independently -- make sure it really works
  correctly before going on to the next step.
