APS105: Computer Fundamentals
Winter 1999

Old APS105 News

Lecture room change!!!

Bad weather day!!!

• choosing variable names (textbook pages 43-44, appendix A2.2)
• constant variables (using the word 'final', textbook 2.4)
• boolean variables (textbook 4.9)
• boolean operators and expressions (textbook 4.7, 4.2)

More bad weather!!!

I haven't taught everything needed for your second lab so it is postponed. I'll decide on Monday the final schedule, but I expect to make both lab 2 and lab 3 due on the following week.

You should still try to work on it at home if you can, or over the internet. Run the 'telnet' program and use it to connect to 'skule.ecf.toronto.edu'.

To help you write your program... keep things simple at first and then add to it. Begin by asking for the values of a, b and c, and computing the two roots without regard for the corner cases. Gradually add things to this... for example, add a test of the discriminant (b*b-4*a*c) to see if the roots are complex, etc.

Project Proposals

Project Suggestions

You must email me your topic before the lab.

Before the lab Monday/Tuesday (March 22/23):

• You must email me your topic. Uniqueness is important.
• have your proposal written up
• have two copies (the TA will keep one)
• include a word description, block diagrams, pseudocode
• describe everything you want to accomplish in your program

In the lab Monday/Tuesday (March 22/23):

• talk to the TA, ask them to help you finalize what you want to accomplish
• try to finalize your pseudocode
• you should complete your "can I do this?" investigation
• TA can help you get organized, tell you how to do things

On Friday (March 26):

• hand in your FINAL proposal in lecture
• proposal itself is not worth marks, but ...
• it specifies the scope of your project, what your goals are
• your marks will depend on whether you meet your goals
• 8 marks for design, 4 marks for completeness

On Project Demo Day (April 5/6):

• code ready for marking IMMEDIATELY
• show off to classmates, invite your friends
• a small working program is MUCH better than a large, non-working one
• make sure you are marked by your TA during the demo
• you will SUBMIT your source code after your demo
• CHANGE: report handed in during last class (April 9), not in lab

Project Suggestions

On Project Demo Day (April 5/6):

• code ready for marking IMMEDIATELY
• show off to classmates, invite your friends
• a small working program is MUCH better than a large, non-working one
• make sure you are marked by your TA during the demo
• you will electronically submit your source code after your demo
• CHANGE: report handed in during last class (April 9), not in lab

Instructions for Electronic Submission of Projects

• please submit ALL FILES we need to run your program
  • ALL .java files, plus
  • any .html files, plus
  • any .jpg files, plus
  • any special files (eg, a dictionary of words)
  • perhaps a README.TXT file to describe each file and identify which has your "main" program
  • anything else you think is needed
  • (we can create .class files ourselves, they aren't necessary)
• use the Unix submitaps105s command to submit your files:
       submitaps105s part# File1.java File2.java ...
• Monday Lab Students: change part# to 1
• Tuesday Lab Students: change part# to 2
• for example, a Monday lab student may run:

            submitaps105s 1 MyProgram.html MyProgram.java Stdin.java image1.jpg image2.jpg
  

• to see what files you have submitted:

            submitaps105s -l 1
  

• you may run submitaps105s more than once, each time overwriting your previous submission.
• you may choose to bundle your files into one jar file, and submit that instead. when using jar, be sure to include the .class files too (it's meant for bundling more than 1 class together):

            jar cvf MyProgram.jar MyProgram.html MyProgram.java MyProgram.class Stdin.java Stdin.class image1.jpg image2.jpg 
            submitaps105s 1 MyProgram.jar
  

• you must use a 'jar' file if you are using subdirectories. for example, to bundle all .html, .java, .class files, and all .jpg files in the 'images' directory):

            jar cvf MyProgram.jar *.html *.java *.class images/*.jpg
            submitaps105s 1 MyProgram.jar
  

• to list the contents of your .jar file:

            jar tvf MyProgram.jar
  

• the downside of using jar: you cannot ask submit to tell you which files are included in the jar file that was submitted
• you cannot remove submitted files
• if you want us to 'ignore' any files you submitted, please tell us in a README.TXT file and SUBMIT IT SEPARATELY outside of your jar file (though you should also include it in the jar file)

Java Programming Reference Material

• Sun's Main Java Site
  
• For Java programmers: Frequently Asked Questions (FAQ) -- with answers
  
• The Java Language Specification (very technical)
  
• Java Packages, 1.1.5 Core API (access from anywhere)
  
• SGI Java Documentation (access only from skule.ecf)
  
• SGI Java Packages, 1.1.6 Core API (access only from skule.ecf)

Getting Lab 8 marked

You can also get Lab 8 marked in the lab on March 8/9. Otherwise, you can get it marked any time before the last lab week, when you demonstrate your project.

Lectures This Week

Project Final Reports

After lecture, you can drop them off at LP374E. Slide them under the door if you must.

Final Exam

The final exam has 6 questions. Some of the questions have more than one part (part a, part b, ...).
You can view the front page now in PDF, or PostScript format.

Office Hours
I'll be in the office (Pratt 374E) on Friday at 4:30pm and Monday at 4:30pm. I will have most of the Lab Exams (Part 1) ready to hand back. I don't think the TAs have finished marking the projects.

Study Problems
Here's what the final exam looked like last term. Choose either the PDF or the PostScript formats.
Here's the list of study problems and textbook reading since the beginning of the term.

Error in Textbook on Binary Trees
There is an error in the textbook, on pages 530 and 531. At the top of page 530 it discusses the insertion of elements into a binary search tree. If you do it in the original order that they suggest, you end up with the tree shown in Figure 13. The book incorrectly states that Figure 13 is the "reverse order" tree. Figure 14 is just another way of looking at Figure 13.

If inserted in reverse order, the tree should look like Figure 15 (when it is drawn in the same style as Figure 14).

Lecture Notes
Please note there was an ANOTHER error in the online lecture notes for lectures 37/38. I had inadvertantly left the old notes online, so you didn't get the corrected version. I have fixed the problem, and also created an update for just the corrected pages in PostScript and PDF formats.
