Programming Languages and Compilers COMP3131/COMP9102 26T1

Assignment 3 Spec Released

Posted by Jingling Xue Wednesday 04 March 2026, 11:02:00 AM.

Dear COMP3131/9102 Students,

I have just released the specification for Assignment 3 (due on 18 March), a few days before Assignment 2 is due. There is some overlap between the two, as they are both part of the same overall assignment. Once you have implemented a parser in Assignment 3, the recogniser developed in Assignment 2 will no longer be used in future assignments. For this reason, no reference solution will be provided for Assignment 2.

In today’s lecture, I will cover how to write a parser for VC.

LL(k): Slide 217 from today's lecture (Mon 2 March)

Dear COMP3131/9102 Students,

I have updated the last bullet point on Slide 217. Since you will have the opportunity to develop a top-down LL(1) parser, you are expected to have a general understanding of LL(k) grammars, at least for LL(1) and LL(2).

See the updated slide below:
