Mr. Joshua StoughAugust 22, 2007

Monday/Wednesday/Friday 3:00-4:15Gardner Hall 307

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.

• Present new material

• In-class exercises– Working together in class is fine.

• Lecture notes are posted, but may be modified shortly after lecture.

• Notebook computers please.

Recitation once per week• Mini-lab led by me

– extra programming practice– I can answer questions from lecture

• You will work in groups

• Each group should always have a laptop and textbook

Textbook

RequiredJava Programming: From Problem Analysis to Program Design D. Malik, P. Nair ISBN: 1-4239-0135-50-619-06497-8 (old edition)

Software

• Java SDK.• jGRASP

– on public lab machines• All Programs / UNC Courseware / COMP

110

– you can install on your machine• this Friday's recitation

• We’ll do a tour later...

Computer Labs

• 7 Labs• Maintained by UNC ITS• You may do homework there

(jGRASP is installed on all UNC lab machines)

• All computers have jGrasp.

Grades

• assignments 60%– both programs and book

• midterm 10-20%• final 20-30%

– If the final is an improvement over the midterm, it may count more.

• total 100%

Assignments

• Please submit electronic copies by 11:59PM on the due date. – turn in using Blackboard

• Homework assignments from textbook– practice for exams

• Programming assignments– budget 10-12 hours per program

• design, code, debugging

– start early!

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 SystemAndrew 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

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!

http://help.unc.eduhttp://help.unc.edu962-HELP962-HELP

• For help on general computer problems, including getting AFS enabled on your laptop or at home

• Also, for free software

Collaborating

• You should– Struggle with the material before

seeking help.– Come to office hours, email me.– Make sure you understand the

solutions you receive help on, whether from fellow students or me.

Sending Email to me

• Put COMP 110 in subject line

• For example:– COMP 110, I’m lost– COMP 110, This course is too easy

Homework 0

• Introduction to Blackboard– 10 points– See Blackboard or Course Schedule

• Due Monday (Aug 27) at 11:59pm• Write a text document and turn it

in using Blackboard
