## Course information

This course is an introduction to the theory, design, and implementation of programming languages. Topics covered in this course include: formal semantics of programming languages (operational, axiomatic, denotational, and translational), type systems, higher-order functions and lambda calculus, laziness, continuations, dynamic types, monads, objects, modules, concurrency, and communication.

See the lecture schedule for more detailed information on topics covered.

or discussed on Ed.
Questions related to grades, special consideration, etc. can be sent directly to Prof. Amin. In general, **sending email to individual course staff will delay a response**. Note
that course staff may take up to 48 hours to
respond.

### Time and place

Tuesdays and Thursdays, 1:30pm-2:45pm, remotely.

### Prerequisites

Computer Science 51. Also
recommended is Computer
Science 121. Students must have **good programming skills**, be **very comfortable** with **recursion,
proofs, basic mathematical ideas and
notations, including sets, relations,
functions, and induction**. See the schedule for some suggested background reading on some of these concepts. Feel free to contact the instructor if you have questions about the requirements or other aspects of the course.

Two points to emphasize: (1) this is not an introduction to programming; students should already know how to program, ideally in at least couple of languages. (2) you must be **very comfortable** with **recursion, proofs, basic mathematical ideas and
notations, including sets, relations, functions, and
induction**.

Try the self assessment to help figure out whether you have sufficient mathematical preparation for this course.

### Homeworks, exams, and grading

There will be an in-class midterm and a final exam. There will be about 6 homework assignments. Some of the assignments will contain a programming component in OCaml, Coq and Haskell and some other languages. Prior knowledge of these languages is not required.

- Midterm: TBD.
- Final exam: TBD.
- Homeworks: 6 assignments. Some will contain a programming component in OCaml, Coq, Haskell, and other languages. See the Schedule page for due dates, and the Assignments page for details of the assignments.

Your grade will be determined by a weighted average of your scores on homework assignments, the midterm exam, the final exam, and class participation. The percentage breakdown (roughly and subject to change) is 50% homework assignments, 20% midterm, 25% final exam, and 5% participation (which includes attendance and participation in class, section, and office hours, and contributing to online discussion).

### Textbooks

There is no required textbook for the course. In most cases, the class materials should suffice. The instructor will provide written lecture notes where helpful.

See the Resources page for additional material that you can examine.

### Lectures/schedule

See here for more information.

### Section

Sections are held:

- TBD
- Weekly Coq section: Friday 3pm-4pm on Zoom (see Canvas for link)

Section attendance is not required. All sections in the same week will cover the same material. Sections will, for the most part, focus on worked examples and exercises to consolidate material covered in the previous week in class. You should feel free to come to section with questions. We will release practice problems a few days before section. More information can be found here.

### Office hours

Professor Amin holds office hours for 1 hour immediately after the Tuesday lecture, in the same Zoom room.

TF office hours are held using Congregate - see Ed for the URL.

We will use this Google calendar for TF office hour times:
