Principles of Programming Languages

Level 3/H

Achim Jung Hayo Thielecke Semester 2 10 credits
Co-ordinator: Achim Jung
Reviewer: Peter Breuer

The Module Description is a strict subset of this Syllabus Page.

Aims

The aims of this module are to:

  • introduce the central ideas and techniques in the theory of programming languages
  • exhibit some of the building blocks from which high-level programming languages are constructed
  • illustrate how concrete languages realise abstract programming language ideas
  • explain ways for defining the semantics of programming language constructs in a rigorous fashion

Learning Outcomes

On successful completion of this module, the student should be able to:

  • demonstrate fluency in reading, constructing, and manipulating expressions in the lambda calculus
  • execute specific evaluation strategies for lambda calculi with effects
  • relate features of concrete programming languages to abstract principles
  • assign types from various type disciplines to program expressions

Teaching methods

2 hrs of lectures and one exercise class per week, two revision lectures

Assessment

  • Sessional: 1.5 hr examination (80%) and continuous assessment (20%).
  • Supplementary: By examination only.
