CS 116
Introduction to Programming-II (C++)
Summer 98

Homework 0 - Due Wed 7/29/98

• Log on to classes.cs.uchicago.edu. For example, if you are using a Macintosh computer in the CS Dept's Maclab, simply start up Telnet, do "Open Connection", and type in "classes.cs.uchicago.edu" replacing the highlighted default machine name. Now use your harper login and password.
• Now you are in an interactive UNIX "shell": you can type in UNIX commands and the computer will perform them for you. Experiment around with UNIX - There is a handout outside my office that takes you through the basics.
• Now it's time for you to learn Emacs. Run emacs by typing "emacs" at the UNIX shell prompt. Type "C-h t" (that is "Control-h" and then "t") to start up the tutorial, which will teach you the basics of Emacs. The reference sheets handed out in class comes will come in handy, although at first you will only be using a handful of Emacs commands.
• Having learned the basics of Emacs, you now know how to create and save files.
  • Using Emacs, create a file called "main.cc" containing one of the simple programs we discussed in Monday's class. Don't forget to save the file.
  • Exit Emacs.
  • At the UNIX shell prompt, type "g++ main.cc -o main". This will turn your program into an "executable" file, i.e. something you can run. The name of this executable will be "main". You can use the UNIX "ls" command to see that the executable file "main" appears in your directory.
  • Run your newly created executable by typing "main" at the UNIX shell prompt. At this point, "main" should create the output discussed in class (Like "The colume of the box car is ...").
• That's it. You are encouraged to experiement around. If any of the above steps give you trouble, send me email.
