Program Five

You should use a good functional decomposition in planning this program.

You should write good structured code that is well documented.

A teacher manages a class using four files. These files are as follows.

• MainFile for each class.
  • This file contains the following
    • Class Name, Number, Year-Term
    • Homework Max_Homeworks Weight homework_file_name
    • Program Max_Programs Weight program_file_name
    • Test Max_Tests Weight test_file_name
    • Finally the file consists of a series of student lines.
      • Student First Name
      • Student Last Name
      • Student ID
    • For Example

      Intro, 130, 2001-Fall
      Homework  4  .05  homework.txt
      Program   6  .45  programs.txt
      Test      4  .50  test.txt
      Bill Anderson  2345
      Sue  Davidson  5432
      Bryan Donaldson 1134
      Steve Smith     9893
             

• Homework File
  • Each line contains
    • Student number
    • A list of homework scores followed by a -1

    • 9893 700 20 -1
      1134 88 90 86 84 -1
      2345 100 65 -1
      5432 87 87 87 87 -1
      	  

  • Program File
    • Student number
    • A list of program scores followed by a -1
    • See the homework line for an example.
  • Test File
    • Student number
    • A list of test scores followed by a -1
    • See the homework line for an example.
  The files are in the format given, but not in any particular order, in other words, you count on the student id being present in a file, but it may be sorted in other orders.

  If a student is missing a score, ie only 5 of 7 homework scores are recorded, then they receive a 0 on all missing scores.

  You may assume all scores are between 0 and 100

  For the homework, the professor has decided that the students should drop their lowest grade (the 0s mentioned above count as a grade). Your program should do this automatically.

  You should read all of the data for each student and calculate a weighted average for the class score.

  Output for your program should be a table:

  
  Intro, 130,  2001-Fall
  
  Name              ID    Hmwk    Prog   Test   Class
                          Avg.    Avg.   Avg.   Avg.
  Anderson, Bill   2345   50      55     75     64.75
  Davidson, Sue    5432   70      87     87     86.15
  Donaldson, Bryan 1134   90      88     92     90.10
  Smith, Steve     9893   30      90     33     58.50
  
  

  You should prompt the user for the name of the main file.

  You should use your editor to create test files for your program.

  Please make sure that you document your program, use proper indentation and variable names.

  When the program is complete, please send a copy to dbennett@edinboro.edu, the subject of your message should be program4, csci 130

  This program is due Monday, November 26 at 11:59 pm.

  This program is worth 10 points.
