Basic Barber Shop Project Grader Sheet
Notes to the Grader for the Runs!!

What follows is the grading sheet for Basic Barber Shop Project related to grading the Runs of a working barbershop.

  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.

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.
