Undergraduate Course: Types and Semantics for Programming Languages (INFR11114)

Course Outline
SchoolSchool of Informatics CollegeCollege of Science and Engineering
Credit level (Normal year taken)SCQF Level 11 (Year 4 Undergraduate) AvailabilityAvailable to all students
SCQF Credits10 ECTS Credits5
SummaryType systems and semantics are mathematical tools for precisely describing aspects of programming language. A type system imposes constraints on programs in order to guarantee their safe execution, whilst a semantics specifies what a program will do when executed. This course gives an introduction to the main ideas and methods of type systems and semantics. This enables a deeper understanding of existing programming languages, as well as the ability to design and specify new language features. The course also introduces relevant parts of logic and discrete mathematics used to describe types and semantics.

Learning Outcomes
On completion of this course, the student will be able to:
  1. Write inductive definitions and prove properties of them using induction.
  2. Exploit the connection between logic and type systems, where propositions correspond to types and proofs correspond to programs; understand how conjunction corresponds to products, disjunction to sums, and implication to functions.
  3. Read and understand the presentation of operational semantics and type systems via inference rules for lambda calculus, and be able to modify such a presentation to include a new language feature, such as exceptions.
  4. Write a formal semantics for a programming language in the operational style, given a careful informal description of the language.
  5. State and prove the preservation and progress theorems that link operational semantics and type systems.
