Lecture 11 – October 2, 2007

 

 

  1. You will have a program due to be electronically submitted next Monday night by 11:59pm.   If after submitting it you discover that you have forgotten to submit part of it, you need to send me an e-mail asking me to clear your submission so you can re-submit it with everything required in it.  Please do NOT send me e-mail attachments of what you neglected to submit.  They will be deleted.

 

  1. You will have an exam in the not too distant future.  You should have learned much more than to write simple FORTRAN and Pascal programs.  In class we looked at the beginning of a detailed outline of items which have been covered in the process of talking about FORTRAN, Pascal, Alice and mini-language Core.  We went over a few items on the list expanding them but not necessarily completing the expansion.  The list for each section has been posted under assignment Review1 on Blackboard.  You should download the document and complete as much of the outline as you can before class on Wednesday and submit it.  Be sure you use the outline for your section.  This will be graded so do as much as you can.

 

  1. We started to expand the outline for Chapter 5 in the 12:30 section but did not get to it in the 2:00pm section.  Below you will find as far as we got in the 12:30 section.  All of you should copy it and as you read chapter 5, expand and complete it. 

 

  1. A link to the textbook slides for Chapter 5 is available on the Web page.

 

  1. We also looked at two different Pascal programs illustrating the declaration and use of Pascal pointers.  Variations of those programs are posted on the webpage and you should play with pointers as soon as possible. 

 

  1. Graded assignment “Things to Verify” was handed back in the 2:00pm section.  Work from the 12:30pm section can be found outside my door.  Note that the total possible points was 25 not 50 as was originally shown on Blackboard.   You earned 3 points for a correct answer; less for one that  was only partially correct or wrong.  I expected to see the code if you discovered something by experimentation .

 

NOTE:  when you submit electronic copies of Word documents, be sure they are saved in Word97-2003 format so that I can read them in my office and on my home machine.

    • Reserved words
    • What does first character have to be?
    • Do names implicitly identify types?
    • What characters can be used in names?
