Course Description
Covers basic concepts of the design and implementation of programming languages, including data representation and types, functions, sequence control, environments, block structure, subroutines and coroutines, storage management. Emphasizes language features and implementation, not mastery of any particular languages.
Audience
This is a core course required by all graduate Computer Science students and is an elective for graduate Software Engineering students. The course is available to other students with sufficient programming experience (see prerequisites) who have an interest in programming languages (e.g. Information Systems, Computer Engineering, etc.).
Course Themes
  1. Evaluation and implementation of of programming languages
  2. Tools for describing and analyzing languages, including syntax, semantics, and pragmatics
  3. Tools to design new languages
  4. Programming Paradigms (imperative, functional, logic, object-oriented
  5. Implementation of programming languages
Course Objectives
  1. Be able to compare and evaluate different programming languages and implement different programming constructs and features (e.g. variables, loops, procedures, dynamic memory).
  2. Be able to formally specify the syntax and semantics of programming languages.
  3. Be able to write a parser and a scanner.
  4. Be able to write a translator to convert from one language to another.
  5. Be able to describe the semantics of and implement an interpreter and compiler for a simple programming language.
  6. Be comfortable with the major programming paradigms and be able to use at least one language from each paradigm.
Course Benefits
  1. Easier to express algorithmic ideas
  2. Better able to formally express concepts
  3. Improved ability to select appropriate languages
  4. Easier to learn new languages
  5. Understand the significance and impact of language choices and constructs
  6. Able to design new languages (little languages, interface specifications, protocols)
Prerequisites
Assumes familiarity with the basics of logic (predicate calculus), recursion and induction, automata, and grammars. All students should be proficient with at least one object-oriented programming language (e.g. java, C++), and it would be helpful to have seen at least two different programming languages.

Grading

  1. Homework and participation (50%)
  2. Midterm (25%)
  3. Final Exam (25%)
Students will be assigned to groups (4 students each - members may come from either the in class or online sections). Each group will be responsible for weekly homework (8 total), and each member will take the lead on two of the assignments. Peer grading will be used for group participation and discussion groups will be set up in webct for each group and all members are expected to participate in the discussions and contribute to every assignment. Doing all of the assignments will be essential for the exams.
