1. EXAM #2
The second midterm is on Wednesday March 30. Attend the section which corresponds to the lab section for which you are registered. The locations for the exam are:
MORNING section: 10.25am-12.25pm in room 337 MUDD
AFTERNOON section: 12.25pm-2.25pm in room 403 IAB
The usual rules apply -- you can use ONE page of notes and you cannot use any electronic devices. The material on the exam will include C, regular expressions (in sh and perl), sh scripts, unix filters (cut, grep, sed, sort, wc) and basic makefiles (as we did in class today).

In response to an unusual number of queries and issues, I have posted my submission policy in order to clarify explicitly the types of confusion people seem to be having this term understanding what is expected with labs and homework assignments.

if you can't get c++ core language, then try getting this:
Ray Lischner. (2003) C++ in a Nutshell: A Desktop Quick Reference, 1st Edition (isbn 0-596-00298-X) publisher: O'Reilly.
here it is at oreilly.com
I have ordered this at Labyrinth and it will hopefully be here before Spring Break. You will need a C++ book starting after Spring Break.
