Course Objectives

In this course, you will learn the foundation concepts and principles of computer science; fundamental computer programming principles, methodologies, and techniques; and basic concepts of programming in general and the C++ language specifically.

Course Website

The URL for the main course website is https://cs.ucla.edu/classes/fall23/cs31. You must check the site for announcements at least every other weekday. You must also check your email as regularly. The course Bruin Learn site is used mostly to house Zoom links to lectures and learning assistant workshops; recorded lectures and workshops; and material posted by TAs.

Textbook

The required course textbook is an interactive online zyBook that offers a number of advantages over static text-dense textbooks. To purchase a subscription ($89):

  1. Sign in or create an account (upper right corner) at https://learn.zybooks.com
  2. Enter zyBook code: UCLACS31SmallbergFall2023
  3. Subscribe
Some of the interactive activities will be required assignments. If you have any questions/issues about administrative aspects of zyBooks (access issues, etc.) contact support@zybooks.com or look at the Students section at the zyBooks help center.

Lecture and Discussion Sections

Lectures will present the material you'll need to know for this class, expanding on material from the course textbook. In discussion sections, your TA along with a learning assistant (LA) will pose problems to solve collaboratively in class to help build your problem solving skills and ensure you understand key concepts. They may answer questions that arise about these concepts, lecture topics, and programming projects.

Assignments

You cannot learn how to write programs without writing programs. There will be several programming projects. Each project specification will detail any requirements that differ from the general project requirements. Your program correctness score is based on your program's correctness as determined by our testing. The amount of time you spent working on the program is irrelevant; indeed, if you follow our software development advice, you'll probably spend less time and get a higher score than if you don't.

Some assignments will be activities in the course text designed to help ensure that you understand important concepts.

Occasionally you'll be asked to fill out a brief online form (e.g., because we need to gather some information for planning purposes) in a timely manner. These "responsibility assignments" will be so labelled and completing them will be worth a small part of your grade.

Every C++ program you turn in for this class outside of the course text must run successfully using two compilers, as specified in the Project Requirements document.

Programming projects are due at 11 PM on the dates below. Unless stated otherwise, late submissions will be penalized by 0.0034722% per second (which comes to 12.5% per hour), making a submission worthless if submitted after 7 AM the next morning. It is your responsibility to start early and to make backups to removable devices or to online storage.

Project 1 Tuesday, October 10
Project 2 warmup Saturday, October 14
Project 2 Thursday, October 19
Project 3 warmup Wednesday, October 25
Project 3 Wednesday, November 1
Project 4 part 1 Sunday, November 5

Project 5 part 1 Monday, November 13

Project 6 Monday, November 27 Tuesday, November 28
Project 7 Thursday, December 7

Examinations

The midterms will cover material from the lectures. The final examination will cover material from the entire course. Missing the final for any reason will result in a final exam score of zero.

Grading

Your grade in the course will be determined from your total score, although a final exam score below 40 may subject you to a failing grade regardless of your total score. The total score is determined from the graded materials as follows:

Projects (excluding zyBook assignments)42%
zyBook assignments  7%
Responsibility assignments  1%
Midterm 1  7%
Midterm 213%
Final exam30%

The weights of these components may be altered if unforeseen circumstances affect an exam offering.

The total points you earn from assignments (scaled to 0 through 100) will be capped at 30 points above the mean of your exam scores (scaled to 0 through 100). For example, if you average 90 on the assignments, your midterm scores are 50 and 60, and your final is 40, then your assignment average is treated as only 80 (because that's 30 more than the mean of 50, 60, and 40). In other words, your assignment scores won't count fully if you can't show from your exam scores that you learned what you should have from the assignments.

A request for reconsideration of the grading for an item must be made within one week of our sending you your score for that item.

Be sure that you have read and understood our expectations about academic integrity.
