CS 442 Principles of Programming Languages


Watch a video introduction to this course on YouTube.

Objectives

To provide an exposure to important abstractions and issues in contemporary programming languages. To explore fundamental programming methodologies, such as functional programming, logic programming, programming with abstract data types, and object-oriented programming. To provide an introduction to formalisms for describing programming languages.

Intended Audience

CS 442 is intended to be taken in the fourth year of a CS major academic plan. The course is of interest to students wishing to critically explore the breadth of programming methodologies. The course will be of interest to those involved in the construction of software in all application domains.
