Prerequisites
 
Important Information about the Class Projects
The class projects will take more than 5,000 lines of C/C++ code to be developed on a UNIX environment. 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!
