1. Look at the output runs and use those to determine if the programs work. if you have real questions then we can ask for a realtime run at a later time.
2. As far as bad inputs, input3.1, there is no specified operation - quiting is fine or just doing defaults is fine. what is not fine, is to crash.
3. Note: Some people found major problems in their code and modified it (after talking to me). Somewhere this should be noted in their comments. They lose 5 points.

Introduction

20 for the runs. If the student has highlighted the runs appropriately, grading should be quick.

• 5 Points max for correct performance on each of the 4 input files. They either work, are highlighted, and commented or they are not.
• If the highlights and comments do not cover the following, then take off points:
  • 10 points if they did not highlight and comment.
  • 5 points if they did not comment after highlighting.

Input Files:

1. input3.1 -
   • consumer sleep = -1
   • print shop contents
   • producer sleep = -3
   • highlight: start of the program, final counts
   • Demonstrates: tests the robustness of your argument checking.
   This is the original input with lousy start parameters. Recovery is actually your choice, but you must recognize the bad parameters.
   2 grunts, 3 noncoms, 3 officers
