  • 6/30/2011: My office hours have been moved. After lectures, I will stay in ZHS 163 to hold office hours. I will set the time for the office hour to be from 11:40am to 12:30pm. As soon as no one is left to ask questions, I will leave ZHS 163 and head for my office (SAL 228). If you need to talk to me about something that you don't feel comfortable to discuss in front of others, you can talk to me when I walk back to my office or you can make an appointment.

  • 6/25/2011:
    • Registering with the class mailinglist is required for this class. This is not the same as the class discussion Google Group. You will be receiving HW and exam scores through this list via individual e-mails. If you have not done so, please visit the mailinglist page after the semester starts. (You do not have to be registered for the course to register with the class mailinglist.) In the registration confirmation e-mail, you will also get your user ID and password for accessing protected area of this web site.

    • Watch this area for important announcements.
 
Prerequisites
CS 102L (Data Structures) or graduate standing. It is assumed that you know how to write programs in C/C++, and how to debug them and make them work correctly under the UNIX development environment.
 
Important Information about Programming Assignments
All graded homework assignments are programming assignments to be done in C/C++. No other programming language will be accepted and your program must compile and run with a Makefile on nunki.usc.edu. (Sorry, no Java.) You must be familiar with the UNIX development environment (vi/pico/emacs, cc/gcc or g++/CC, make, etc.)

If a student signs up late for this class, he/she is still required to turn all projects and homeworks on time or he/she will receive a score of 0 for these assignments. No exceptions!
