+
There may be many different ways to edit a program to make it output the one specified in the problem.  In general, if you have a choice between several possible modifications, pick the one that is the simplest.  Do not try to rewrite the program, but keep its structure.  It is acceptable to add new statements in some problems.  You can click on the '''evaluate''' button to see whether your program is correct or not. The evaluate feature will be available for the first half of the semester.

+
You should work as a pair on this assignment, and submit your program on Moodle twice, once for each member of the pair.  For example, if Emily and Sarah work as a pair, they will create the program together on one computer.  When the program runs well, Sarah will connect to her Moodle account, and submit the program in the area specific to this assignment, and then Emily will connect to her Moodle account and do the same.

'''Grading''':  The homework assignments count for a total of 40% of the final grade.  Since there will be approximately 11 assignments this semester, each one will count for roughly 40/11 or 3.9% of the final grade.  Homework 1 contains 10 problems; therefore each one counts for approximately 0.039% of the final grade.  The programs are graded 0 or 100, depending on whether its output is exactly the one required, or not.
