CSC3321 : Understanding Programming Languages

Semester 2 Credit Value: 10
ECTS Credits: 5.0


Programming languages come and go - if you make a career in computing, there is no doubt that you will have to learn languages which do not even exist today. (In addition to literally thousands of general purpose languages, there are those tailored for specific applications like virtual reality, text layout, robotics, ...) Sadly, many languages embody one new idea (e.g. objects, remote execution) but are significantly *worse* than their predecessors in other respects.

The principal aim of this module is to communicate ways of understanding and documenting the key ideas in a language. The material should equip you to make sense of the many languages you will meet in your career. If you design new languages, they will benefit from you being able to manipulate the key concepts.

Outline Of Syllabus

Introduction - syntax versus semantics
Syntax - 2 weeks (concrete versus abstract; context conditions).
Semantics (meaning) - 8 weeks
(Focusses on the "Structured Operational Semantics" technique.)
Revision/other approaches - 2 weeks.

Covering large definitions (PL/I, Ada, Java) and different (to SOS) approaches

Assessment Rationale And Relationship

The exam is a problem solving task - it is "open book" - there is no need to learn anything by heart for this module.
The coursework is done in groups (with a small individual element) but each student has to present their own portfolio for marking - other than the (small) individual element, text can be shared between members of the group.
There is one piece of coursework (with five elements of equal weight) requiring students to demonstrate their understanding of both syntax and semantics of programming languages.

N.B. This module has both “Exam Assessment” and “Other Assessment” (e.g. coursework). If the total mark for either assessment falls below 35%, the maximum mark returned for the module will normally be 35%.
