CPSC 231: Assignment 5 Marking Key

    Max score

Coding style (marks may be awarded independent of program functionality)

 
  Follows basic style conventions which includes: good naming conventions, easy to under stand code, using named constants, good error handling,

(Never = 0 marks)    (Sometimes = 2 marks)    (Mostly = 6 marks)    (Always = 8 marks)

8
  Class attributes are logical to the definition (e.g., not variables that are just local to a function or method but belong to each instance) 2
  Penalty: Boolean and mathematical expressions are not simple and easy to read -4
  Penalty: gross inefficiencies in program code (e.g., duplicated program code via cut and paste) -4
  Penalty: global variables employed (other than the debugging flag or flags) -4
  Class Pursuer does not consist of at least three methods (init(), a method to generate the report and 1+ methods to generate an interaction -4
  Class Target does not consist of at least two methods (init() and a method to generate the report -4
  The definition of class Pursuer does not include all the minimum attributes specified in the assignment description -2
  The definition of class Target does not include all the minimum attributes specified in the assignment description -2
  The Manager module contains at least two functions -4
  The code for the 2 classes and the manager functionality is not included in its own module (and in the correct module) -9 (3 each)
  Special penalty: employ classes and objects 1.7 regardless of other style, documentation or functionality marks

10

Documentation (marks may be awarded independent of program functionality)

 
  Header documentation: contains overall description of program. 3
  Header documentation: demonstrates some form of versioning system employed (date or version #) 1
 

Provides an accurate list of features / limitations (functionality not implemented) in the program  (1 marks for each feature listed as completed or as not completed x 14 features listed below). Miscategorizations or other inaccuracies will not be awarded marks.

14
  Penalty: Name, ID and tutorial section not included in the header documentation -6
 

Sub total for documentation

18

Functionality (only qualify for these marks if the program runs)

 
  Prompts user for the number of interactions (that the date will consist of) 1
  Runs for the specified number of interactions 1
  Prompts user for the probability of type 'x' interactions exhibited by the Target 1
  Error handling: range checks that the no. of interactions >= 1 1
  Error handling: type checks the no. of interactions, uses exceptions to handle non-numeric or non-integer values as specified in the assignment 2
  Error handling: range checks that the probability of 'x' interactions is within the range:  0 <= P(x) <= 100 2
  Error handling: type checks the probability of 'x' interactions, uses exceptions to handle non-numeric or non-integer values as specified in the assignment 2
  Class Target: Randomly generates type 'x' or type 'y' interactions (equal probability for each) 2
  Class Pursuer: Randomly generates type 'x' or type 'y' interactions (equal probability for each) 2
  Class Pursuer: Can determine the result of each interaction 2
  Class Pursuer: Displays 3 required statistics (must be correct) after each interaction has occurred 3
  Class Target: Generates type 'x' or type 'y' interactions  based on the user entered probabilities 4
  Class Pursuer can modify behaviors according to the target's past behavior 8
  Class Pursuer: Displays the 7 required statistics at the end of the simulation 7
