Week 05 Notes for CS 2500 -- Fall 2000

• Take Roll.
• Announcements
  • I finished grading program #1. Check your e-mail for results. Also look at the summary on line to see all the class members' scores.
  • A lot of the students turned in a level one program on the first due date for program #1, instead of the level two program that I assigned. Let's take a quick look at the examples to make sure we understand the difference.
  • Check out what the readings are about this week.
  • No class next Monday (observing Columbus Day)
  • Quiz and program due date next week.
• Most students did not test their program #1 adequately on the scripts. Look at the example script in this directory for a look at "the right way."
• Another important thing to notice about the sample test script: the person making the script cats each input file before running the program on that input.
• The compiler command option for naming the executable file:
  (g++ -o decode decode.cpp)
• Discuss compiling/debugging with jove
  • How to execute the compiler "inside" jove: (C-u, C-x, C-e)
  • How to break out of jove to a sub-shell whilst "saving your place": (M-s)
  • Testing the program while in the sub-shell.
  • How to break out of the sub-shell and return to "your place" in jove: (exit)
• Point out locations in "General Info" section of web space where there is information on compiling, setting up www browsing, and other things ...

• Take Roll.
• Announcement(s)
• Discuss virtues of abstract data typing and modular code.
  • Easier to design correctly
  • Easier to change implementations
  • protects integrity of data from users
  • Easier to re-use code
• Look at the data structures talk
• We can talk about how data structures are built up with arrays, structs, arrays of structs, structs containing arrays, etc.

• Take Roll.
• Announcements
• Discuss an example data structure: a version of the listClass (an array-of-structs implementation).
