CSC 160 Spring 2015 - Homework 10 (100 points)
Assigned Apr 20, due Mon Apr 27
1) Assignments with time stamps during class time (Mon or Wed 4:15-5:30pm) will be given a grade of ZERO.
2) In the spirit of the pair programming article that you read and summarized in HW5, this week's homework assignment may be done in pairs. If you choose to work in pairs, you must find time outside of class to work together in person at one computer. As per the syllabus, you cannot "pair-off" with the same person more than once during the semester. If you choose to do the assignment in pairs, please submit one copy through Moodle where both last names are used in each file name and both names appear as a comment at the top of the Definitions Pane.
3) Start this homework as soon as possible so that you have time to get any help you may need from the instructor or course tutor prior to when the assignment is due.
4) Do not start the exercises until you have fully read and fully understood the corresponding textbook sections. If there is something you do not fully understand, you must contact the instructor or course tutor prior to starting the assigned exercises.
