Final Exam
This exam is given under the rules of the honor code at Smith College. It is open-books, open-notes, and open-Web. The work on this exam is to be done individually, and assistance from anybody other than the instructor is forbidden. TAs are not available to answer questions, and will be asked not to do so. Pair-programming is not allowed.
Any program section greater than a function used and taken from a Web site other than our CSC111 Web page should be cited in the header of your program, or the header of the function.
Questions can only be asked to your instructor, and only via email. Email questions will be returned with an answer to the whole class.
The exam is due on 12/22/11 at 4:00 p.m. Any file received after this date will not be graded. You will need to submit the exam using the rsubmit command, or using a submit Web page, similarly to the way you have submitted homework assignments this past semester. If you are having problem with either one of these submission options, email your file(s) to me before the deadline, at dthiebau@smith.edu.
Important Note: The lab of 12/15/11 will count for 1/3 point of this exam. You will need to demonstrate that you have code one of the last two challenges of the lab to get the points. You can work in pair during the lab, but not for the programming part which is explained below.
