CSC 160 Spring 2014 - Homework 10 (100 points)
Assigned Apr 16, due Mon Apr 28
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 to 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.
