Marking guide for assignment #3
#######################################################################################

The program falls in one of three categories:
   Program does not compile (at most 30)
   Compiles but crashes when trying to run (at most 50)
   Runs without crashing

The marks are divided as follows:
---------------------------------
(15 marks) are given to two test files (students.txt and students2.txt)
       /5 students.txt  - part I
       /5 students.txt  - part II (keys: 2453106, 2087743, 2633582)
       /3 students2.txt - part I
       /2 students2.txt - part II (keys: 2173098, 2225639, 2364551)

Part1: to check whether the bucket, directory and log file is created correctly. Possible errors:
	a. Empty directory, bucket or log files (-5 for students.txt, -3 for student2.txt)
	b. The log file shows that the buckets are not being created correctly (-4 for students.txt, -2 for student2.txt )

Part2:(2 marks) is used to check if the program can search the record according to the directory and bucket file built in part I
	a. Does not give any correct search results for the above keys (-5 for students.txt, -2 for student2.txt)
	b. Give correct search results for some keys (from -1 to -4 depending on the number of correct searches)

(2 marks)   report file not present -2.

Following are 3 different possible cases:
(85 marks)
A) When program compiles and runs without crashing or crashes after producing a good amount of partial results 
-----------------------------------------------------------------------------------------------------------------------
    Possible discounts are:   
    /20 Manipulation of Datafile
    a. Not complete, handling the end of file is not correct (up to -5)
    b. Not correct, get wrong key & rrn (up to -20)
     
    /15 Manipulation/Creation of Bucket File
    a. Initial creation is not correct (up to -5)
    b. Appending lately is not correct (-5 to -10)
    c. Reading and writing the bucket are not correct (up to -5)
    
    /10 Simple insertion 
    a. Insertion is not correct (-5 to -10)
    
    /25 Insertion with Bucket Split (detected in EHBUckets.txt)
    a. Splitting is not correct (-5) 
    b. Redistribution (-5 to -10)
    c. Hashing mechanism, locating the bucket and packing/unpacking the bucket (up to -10)
    
    /5 Correct Directory update
    a. Not correct (up to -5)
    b. Packing/unpacking the directory
    
    /10 Search
    a. Not correct (up to -10)

(50 marks)                   
B) When program compiles but crashes when run, the 50 marks are divided as follows:
-------------------------------------------------------------------------------------
With little or no partial results produced
    Possible discounts are:   
a.  Doesn't give any result, no printout on the screen, no files created (at most 30, depending on the coding effort)
b.  Not complete: lack datafile manipulation (-10)
                  Searching (-5)
                  Bucket/directory file manipulation (-10)

(30 marks)   
C) When doesn't compile,  the 30 marks are divided as follows:
------------------------------------------------------------------------
(Maximum 30 marks depending on partial correctness) possible discounts are:   
a. The program is almost the same as that downloaded from the web (-30)
b. Show very weak coding capability (too many simple compiling errors, like variable not defined.) (-20)
