CS360 Midterm -- October 18, 1999.

There are four questions.
You have 50 minutes.
Do your answers on a separate sheet of paper.
Note, on question 2, you may think that there is a problem with the code. That is intentional. You must pretend that you are a compiler and compile and run the code given.

In assigning grades, I first like to set the basic competence level. Here's my breakdown:

Question 1: Basic competence: 6 points (structure, two tree traversals, checking p->type == 0, printing key.s, details), a good answer should be at least 8 points.
Question 2: Basic competence: 11 points (6 points for part 1, 4 points for part 2, one point for part 3). A good answer should be at least 14 points.
Question 3: Basic competence: 5 points for explaining buffering, and none for convenience. A good answer is 6 points for a lame genuflect toward convenience.
Question 4: Basic competence: 8 points (structure, opendir, return val, traversal, stat return, print name/recursion, initial call) Good answer: 10 points.

This makes 30 points for a B, 38 for an A. Here are the ranges:
