CS 203
 CS 203: Programming With Data Structures is the third course in
the three-term Java Programming sequence.
 This is a critical class for CS majors. All the programming classes
you take after this will build on this material. Accordingly, the
workload will be high, even for a 5-unit course.
 Most class meetings will be split roughly evenly between lecture
and lab time

 Textbook Info
 Grading policies
 Assignments
 Grading: A, B, C, (with + and -), NC.
 If you don’t get at least a C (undergraduate) or B (graduate), you
get an NC.
 Grading standards in this class will be tougher than in my 100
level classes.
 See the grading scale on the syllabus
 No curve
 You will have your midterm grades before the withdrawal-withW deadline
 I have toughened my policy on late work; see the course web
 All assignments will be linked from the course page.
 Hand in via CSNS.
 If you have not previously used CSNS, go to csns.calstatela.edu and login
using your CIN as both username and password. Change your password. Let
me know immediately if you have any difficulties with this.
 If you don’t have a logon to the lab network, get one from the IT staff in the
library right after this class
 Quizzes will consist of multiple choice, short answers, and one-
paragraph writing questions.
 There is a small number of definitions and descriptions you will
have to memorize for this class. Closed-book quiz questions may
test your knowledge of these. Most of these definitions will be
covered in the first two weeks.
 Slides marked “memorize this slide” obviously contain information
likely to be on closed-book quizzes, but I don’t always add that
note. I will always make it clear verbally when you need to
memorize something.
 Most quizzes will be open-book and open-note
 Use the book and notes for on details. If you don’t understand the
material you will not have time to learn it during the exam.
 One midterm, one final exam
 Makeup midterms are allowed with no questions asked, but will
be much more difficult than the original exam.
Since I began this policy, few students have asked to make up
If I write a makeup exam at your request and you don’t show
up for it, you are toast.
 No final exam makeups without well-documented justification.
Individual Presentations
 Each of you will make a three-minute presentation in which you
will explain some of your own code line-by-line
 These presentations will be start in week three. I will hand
around a sign up sheet.
Liang, Introduction to Java Programming, Comprehensive
Version, Tenth Edition.
Be careful to get the right book; there are several other versions.
It is important to get the Tenth Edition, even though older
editions are much cheaper.
• This course covers a large volume of difficult material, and I
can only take time to review only a few key concepts from

Cheating: The Short Version
 Presenting an answer that is copied from any source other than your
brain is always cheating.
 You may not copy code from other students or allow anyone to copy your
 You may not copy text from any source and use it as an answer to any
problem in this class
 Few or none of our assignment questions will be taken from the textbook
or other sources, so don’t bother copying published solutions to the
textbook exercises. You may want to look at them as additional examples
of the material, though, if you trust them to be correct.
 I will punish all students involved in copying equally, even if it’s obvious
who copied from whom.
Cheating on Exams and Quizzes
 Examples of cheating on exams and open-book quizzes:
 Copying code or text from other students or any other source
I can detect copying!
 Answering short-answer questions with direct quotes from the notes
(restate them in your own words!)
 Communicating during an exam or quiz with any human being other
than me via email, chat, phone, or any other means
 You may not directly use language from the lecture notes, textbook, or
any other source to answer short-answer or essay questions. Restate the
answers in your own words.
Not Cheating on Exams and Quizzes
 OK on exams and open-book quizzes
 Consulting lecture notes, textbooks, your own notes
 Checking Wikipedia or other internet sources that do not involve real-
time communication with human beings, and restating the content in
your own words. This is permitted, but it is not likely to be an efficient
use of your time during an exam.
 Copying code examples from the lecture notes or textbook only and
modifying them to answer the questions. I expect you to do this.
Cheating Detection
 It is completely obvious when students answer short-answer and essay
questions with text copied from professional-level sources like Wikipedia
and textbooks.
For Java coding problems, the number of possible correct solutions is very
large, and I am experienced at figuring out when multiple students’ work is
too similar.
If you copy answers you will sooner or later copy an identifiable error
answer or trip up in some other way.
I will be comparing all students’ short answer and essay work using a tool
designed to detect copying.
People who do well on labs but poorly on exams and quizzes receive very
careful scrutiny!
