Homework Assignment 3 Due Tuesday, Feb 20th at 11:59PM (Pacific Time) In this assignment, we will continue to augment . This time, we will add booleans, lists, and recursion. This homework will consist of four parts. The first part gives you lots of practice with the syntax and the operational semantics of the augmented language. …
Homework Assignment 2 Due Wednesday, Feb 7th at 11:59PM (Pacific Time) In this assignment, you will augment the simple arithmetic language in the last assignment with lambda calculus. The resulting language is called . This language is so powerful that it can simulate the execution of any Turing machine, and thus any computer program in …

Assignment 3: PCF, FPC, and PyCF 15-312: Principles of Programming Languages (Fall 2023) In this assignment you will explore concepts of self-reference in programming languages. In PCF we consider self-reference at the term level. Most often students encounter this form of self-reference when defining recursive functions, those that “call themselves” when applied to an argument. …
Assignment 4: Effects: Control and Storage 15-312: Principles of Programming Languages (Fall 2023) This assignment will familiarize you with effects that are widely present in programming language. Effects, or side effects are umbrella terms used to describe any computational phenomenon that is not fully captured in the return value of an expression. Common examples of …
Assignment 1: Statics and Dynamics, Safety, and Finite Data Types 15-312: Principles of Programming Languages (Fall 2023) On this assignment, you will implement the statics and dynamics of a simple programming language, PSF, which has product, sum, and function types. You will also prove that the language is safe, showing some cases of progress and …
