Week 01 Notes for CS 1500, Section 001 -- Spring 2001

• Take Roll.
• Resolve names on lab, lecture lists.
• Get updated wait list.
• See if we need a new room.
• Look at upcoming schedule
• Announcement(s)
  • Week 01 is short: class meets Wednesday and Friday only.
  • First Lab will be on Monday, Feb 19 ( Hello World!)
  • Labs thereafter will normally be on Fridays
  • Show map to P-288
• Pass out course materials:
  • Course Description
  • First page of the class schedule
  • Copy of Hello World! handout
  • Copy of JOVE help handout
• Show text books. Shiflet is for learning C++. Andersen is for learning how to use the Sun Ultra's.
• Pass around a sign-up sheet for new accounts.
• Go over information in the course description.
• Assignment:
  • Students need to read and study the Hello World! assignment to prepare for performing the assignment in lab on Monday.
  • If possible, study the online version -- you will be able to follow links to advice for choosing a password and directions on logging in.
  • You can look at pp. 16-17 of your little Unix book by Andersen to get help on choosing a password.
  • You should have a new password all ready before we start lab on Monday.
• Discuss schedule for today, Friday, and Monday.
• Class must learn to work on Suns
• Each Sun is equivalent to the others.
• Do lab partner assignments. Students may make swaps if they notify me by e-mail.
• Show class where to get hello world handouts and Jove handouts online:
  • Hello World!
  • Jove help

• Take Roll.
• Give update on new room.
• Look at upcoming schedule
• Does anyone need/want copies of the course handout? I have more now.
• Announcement(s)
  • Our department secretary Marlys sent out the following message:

    Please remind your women students in the CS classes the mentor list serv
    is available for them to join.
    
    If you would provide their e-mail addresses, I would like to do an e-mail
    invitation also.
    
    Thanks.

• About Compiling:
  • Computers have their machine language
  • Each micro-processor has its own machine language.
    • In general a different language for each chip, although typically designers make sure that the newer version of a chip model will run all the instructions of the earlier model.
    • The machine language instructions do *really simple* things. It takes a great many of them to do anything of "much consequence."
    • High level languages solve the problem (well, to a degree). High level languages do a lot more with each instruction, and they are portable too. Portable programs are a big plus.
  • Computers need support, or they cannot run high level languages. A computer that could execute C++ instructions natively would be prohibitively expensive.
    • The computer needs a compiler or interpreter -- a program that translates high level programs into machine language programs.
    • Since the machine languages of computers vary, different computers need particular compilers designed to produce their native language.
    • We create a C++ program called hello.cpp with a character-file editor. Word processors don't tend to work well for this purpose because the files they output are formatted with special codes that the compilers and interpreters are not designed to understand. Also, editors for programs tend to include features that are helpful to programmers, such as auto-indent, and integration with compilation. Word processors don't do that. The g++ command translates hello.cpp into a.out. g++ is the name of the compiler. If we do "which g++" or "whereis g++", we can see where the g++ program is in the system. The translated program is called "a.out". We type its name to run the program.
