• [Fri Oct 27 13:00 2023]   We didn't get to go over HW06 Question 1 in class on Thursday. There could be a question like this on the midterm exam. Here's a sample solution.

• [Fri Oct 27 09:00 2023]   Some details on the Midterm Exam this coming Tuesday:

  • The marked up PDF file of last year's midterm (from lecture) on Google Drive.

  • The past attendance quizzes are now available again. Some students requested this as a study aid. (Btw, I never made Attendance Quiz #8 because I forgot to take attendance that day.)

  • Here's a list of topics that are "fair game" for the midterm. The main difference between this and last year's midterm is that we did a lot more on lex and yacc. So, more LR parsing than the sample exam.

    Be ready to:

    • convert arithmetic expression to RPN
    • write regular expressions using PCRE syntax
    • draw a DFA for a set of strings
    • interpret a context-free grammar
    • give a derivation for a sentence for a CFG
    • draw a parse tree for a sentence for a CFG
    • write a CFG for a set of strings
    • step through an LR parser processing a token stream (like in HW6)

    Topics that you should be familiar with

    • categories of PL: functional, imperative, OOP, logic
    • Prolog, Forth (no need to remember syntax)
    • phases of compilation: scanning, parsing, code generation
    • regular expressions & DFAs
    • context-free grammars: derivations, parse trees
    • recursive descent parsing
    • predictive parsing
    • bottom-up parsing
    • lex and yacc
    • early vs late binding
    • lexical vs dynamic scoping

  • [Wed Oct 25 14:00 2023]   Homework 8 posted. Due Thu 11/02/23   Submit on GL only.
