	Fundamental Programming Concepts Summer 2000

Lab 4 Grading

Part	Points
Calculator	10
Correctness (5 points) 4 points for correct answer 1 point for correct output format -3 if doesn't support floating point operands -1 for using float instead of double No correctness points for using any conditionals other than if Robustness (2 points) 1 point for handling division by 0 (can't throw divide by 0 exception or have result of Infinite) 1 point for handling invalid operators Style (3 points) 3 points for correct indentation and consistent bracing of conditionals
PlanetaryWeight
Not graded due to class error in submitting Lab 3 and turnaround time for Prelim 1.
Blackjack	15
Correctness (10 points) 5 points for correctly calculating points in dealer's hand 3 points for correctly determining blackjack/stand/hit 2 points for abstracting repeated tasks with methods Style (5 points) 2 points for correct indentation and consistent bracing of conditionals 3 points for readability of conditionals (penalties for deep nesting, poorly written conditions, way too many else if's, etc. -- take a look at the online solution to see a compact way of doing it)
Miscellaneous Penalties (for each program) -80% for not turning in .mcp file on one program, -50% thereafter Points off at grader's discretion if .mcp file cannot be opened and project run immediately No credit if .java file is missing
Total	25

General comments:

Many of you used a lengthy extended if-else construct on blackjack. Pay close attention to Michael's solution for that problem; it shows a much better approach.
Also, pay very close attention to style. I was lenient in grading some aspects of style, but that's no reason to ignore good programming habits. For example, there is a correct style for capitalizing names of variables, methods, and classes; you may be penalized if you do not adhere to this style. READ THE STYLE GUIDE and follow it.
It should go without saying that there is never any reason to output error messages that are threatening or otherwise rude to users--they would, of course, be bad style. You will be penalized for them in the future.
