About COMP 110
• Learn how to develop algorithms
• Learn the basic components of computer
programming
– can be applied to any programming language
(Java, C++, etc.)
• Is COMP 110 right for you?
• Requirements / prerequisites
– no programming knowledge assumed
– Math, algebra
Is COMP 110 Right for You?
• Do you have web programming experience
with Java, perl, php?
• Experience with “classes” in C++?
• Some experience with Matlab, Mathematica?
• Do you know what is meant by Object,
method, member variable, recursion, array,
sorting algorithms?
• If yes to any, you may be ready for COMP401
instead.

Submitting Assignments
• All assignments will be submitted through
Blackboard
• Submission Errors
– I will email you and give a deadline for re-submitting
– not checking your email is not an excuse for missing
the deadline
Late Policy
• Late assignments are not accepted
• Exceptions will be made as necessary
Working in the Lab
• Before you open jGRASP and start coding
(and asking for help):
–
–
–
–
read the assignment
think about what the assignment is asking for
review lectures and examples on the topic
write (yes, on paper) your plan for completing the
assignment (i.e., your algorithm)
• talk to/email me if you’re having trouble at this point
Campus File System
Andrew File System (AFS)
• Disk space associated with your Onyen
– automatically backed up by UNC
• AFS in the lab
– automatically appears as drive H: when you log in
• On your personal machine
– you can install the AFS Client
– won’t see drive H: unless you’re connected to the network
(i.e., can access the Internet)
• More information
– http://help.unc.edu/?id=215
Backup Your Work!
• Backup your work!
• You will lose something at some point
– you might have to learn the hard way
• Use your AFS space
– use of AFS space is not required, but is recommended
• Search for “backup” in the Windows help
Help!
• For help on general computer problems,
including getting AFS enabled on your
laptop or at home
• Also, for free software
