My (hackified) Project 2.2 Solution

Remember that if you use my solution to project 2.2, you will set your regular credit cap for project 3 at 90%.

I thought I made a mistake with the nil value in my version of project 2.2, but, sadly, I was wrong. I'm sure you'll find some real problems though! Here are some:

• The rule for comments in the lexical analyzer is broken. Fix it.
• make_prim for strings should place a '\0' character in the val.size() element of the ptr array.

Extra credit items for project 3:

• Doing eval - %10
• adding if and while - %5
• doing *rest parameters - %3

Sample input for Project Part 3.

The sample input shows you all sorts of wonderful things. Don't worry about the use of arrays in the example. Arrays, strings, and hashes are still optional.

What about those algebraic specification of abstract data type questions?

I assigned three problems to be done for homework but not to be turned in. You can find the problems and the solutions by consulting the appropriate Homework page.

What's the main program for Project 2 phase 2 look like?
