PIC 20A

Program in Computing 20 A

Office Hours:
• MTR 9:30 AM - 10:25 AM (Dr. Dinov)
• TBA (TA: Yon Seo Kim)

Basis for Final Grade:
• 30% projects & homework assignments
• 30% midterm exam
• 40% final exam

Tentative schedule of examinations:
• Midterm: Fifth week of classes (Mon., July 22, 2002)
• Final: Last week of classes (Thu., Aug. 15, 2002)

• The Java Tutorial, 3^rd ed. by Capione, Walrath and Huml, 2001
• Java Examples in a Nutshell, 2^nd ed. by David Flanagan, 2000

Grading Policy:
The lowest graded programming assignment will be dropped. All programming assignments must be completed however. No late programming assignments will be accepted. For students with genuine documented reasons for missing the midterm arrangements will be made. Programming assignments will be collected from the submit directory of your account.
If after receiving a midterm or programming assignment back you believe a grading error has occurred please see Dr. Dinov or your TA. Reading assignments will be given. You will be held responsible for the information covered in these assignments.

Programming Assignment Policy:
You are allowed and encouraged to discuss general aspects of programming problems with classmates. However this discussion should not involve the exchange of actual code, printouts or other explicit materials (e.g., solution-emails). Namely, the code you submit must be your own independent work. The lowest score on a homework project will be dropped.

General Guidelines:

• Assignments will be posted on online at the class web page ( http://www.stat.ucla.edu/~dinov/courses_students.html). Approximately 5-8 programming projects will be assigned over the course of the quarter. Each project will require you to write a program in Java to solve a specific problem.
• All programming projects must be submitted electronically, by placing your files in the SUBMIT folder in your PIC Lab account. Be sure to give your files the EXACT name required (remember that case matters). Computer programs must be submitted by the time on the due date. Late projects will not be accepted by either e-mail or via SUBMIT.
  
• Leave the homework files in your "SUBMIT" folder for the rest of the course, even after they have been collected and graded. You may be able to submit files remotely with ftp, but it is best to make sure your submission works in the Lab before you submit. If you wish, you may overwrite a previous submission with a new version at any time before the due date. Please do not store any files in your submit directory other than those that are to be or have been collected. To confirm that you have submitted correctly, run the checksubmit program. This check generally requires a trip to the PIC Lab. Your homework scores will be posted in your grade book at my.ucla.edu. Please, check your grade book on my.ucla.edu web site each week to verify your grades. This is very important, it is the only way to know for sure that you actually received credit for your assignment.
• Each program you submit MUST have the following header:
  /*
Name:
Student ID:
E-mail address:
I certify that the following represents my own independent work and
conforms with the guidelines of academic honesty described in the
course syllabus and the undergraduate catalog.
*/
Any homework submitted without this header will not be graded, and you will receive zero credit for it.
• Your code should be as easy to read as possible. Use indentation carefully and consistently to delineate levels of nesting. Disjoint blocks should be well separated by concise and informative comments. This will be worth at least a point on each assignment. Although you are allowed a fair amount of choice in style, please try to conform to the conventions used in lecture and in the textbooks.
• You may use the PIC Computer Laboratory in Boelter Hall 2817 to work on your programming assignments. Use the Java 2 SDK (version 1.3) for your projects. Java^™ development tools are installed on all PC's in the PIC Lab in the following locations:
  • C:\java\jdk131\bin
  If you have your own computer and would like to work at home, you can use your favorite java development environment. However, you must still submit your program to your UCLA class account. To do this, bring a floppy disk containing your program to the lab and copy your files to your class account. Always compile and test your programs on the lab machines before submission.
• Start working on programming assignments early. Do not wait until the last minute to submit your work, as the lab may be full or closed near the project deadline. Deadlines for homework will be strictly enforced.
• You are encouraged to discuss aspects of the course with other students, and you may discuss the homework assignments in general terms with others. You may also get help from the TA or the instructor in designing your algorithmic approach. However, the general rules of academic honesty apply to all homework: each homework assignment must represent your own, independent work. In particular, you may not copy any part of a program written by someone else without citing the reference carefully.
• If you have a question on the way a homework was graded, you must contact the instructor within one week of its return.
• Your programming will improve with practice. After finishing an assignment, do not be afraid to experiment with your old assignments.
