Thurs Sep 11 - Intro Programming Lecture Notes

• Questions

• Any discussion of In the Beginning was the Command Line?

• Go over the design, testing, debugging, maintenance of the mathq.pl program from chapter 3 of the text.
  • Discuss "client's" problem specification.
  • Discuss kinds of programs - command line Q&A vs full blown GUI vs network client/server vs ...
  • Discuss "LP" (literate programming) and Knuth
  • Note that there ways to automate the testing. (We'll do that later.)
  • Redirecting input/output from the command line. (on Windows?)

• Start talking about perl data if there's time.
  • This stuff is written too many places for me to copy it here; I'll just pick out interesting parts from the text and put them into a short program to show you how it works.
  • I wouldn't recommend trying to memorize all this - small parts of the language are enough to get going. Read the references as you need to.
