Individual homework

None this week.

Project

As usual, turn in only one solution per group.

Design and implement the necessary extensions to the PL/0 parser and AST class hierarchy to parse and represent the extended PL/0 language. Use the project description and extended BNF description (available after assignment #2 is submitted) as the language definition.

Thinking carefully about the AST extensions will pay off. One particular pitfall to avoid: an array of arrays is not a 2-D array; PL/0 only has 1-D arrays (whose elements can be of any type, including array).

Turn in:

your files and test cases electronically, and
print outs of your changed implementation, with your changes clearly highlighted with highlighter pen.
