CS150 Fall 2001

Final Programming Project

General Notes :

• Each phase is to be fully implemented before attempting the next phase.
• Your Final project must be submitted by 2:45 PM the last day of the class.(December 6, 2001)
• partial credit will be given for features that are not fully implemented but are stubbed out and well documented with pseudo code.

Phase 1 (20 Points) Due: Tuesday, November 27 by 2:45pm

Develop a class to represent a CS150 Student. Name the class CS150Student. Each student object will have the following eight (8) data members: id number, first name, last name, quiz1, quiz2, final, total lab score, and total project score. The id number will be a 4 digit integer, the first and last name should be strings (or cstrings) and values for all scores will be between 0 and 100. (Note no range checking is needed - assume valid entries will be made for each field).

You must also provide member functions that do the following:

• a default constructor, which sets the id number to 0000, first and last name to empty strings and all scores to zero.
• a 3 argument constructor that takes an id number, first name, and last name.
• a 8 argument constructor that takes values for each data member.
• eight mutator functions, one for each data member.
• eight accessor functions, one for each data member.
• input() - input values into a variable of type CS150Student.
• output() - output the value of a variable of type CS150Student
• average() - compute the weighted average for a student (see below).
• letterGrade(double avg) - compute letter grade based on average (see below).

Write a main function (contained in a separate source file named lastNameP6.cpp) that tests all aspects of your class. Write a main that does at least the following:

• declares 4 variable of type CS150Student - declare variables so one uses the default constructor, one uses the 3 argument constructor and one that uses the 9 argument. Other CS150Student objects should be declared and constructed as needed.
• put values into the variable declared with the default constructor using the input() member function.
• put values into the variable declared with the 3 argument constructor using the appropriate member function.
• output the value of each variable of type CS150Student using the output() member function.
• output the average and letter grade for each student
• output the value of one of the variable of type CS150Student using the accessor functions.

Calculating the weighted score:
The member function average() should compute the weighted average and return this value

the final test score is worth twice the quiz scores, therefore, there are 400 points possible for tests
divide the sum of the test scores by 400 to get a percent of the total
next multiply this percentage by .55 (weight of score) to get testScore component
testScores = ((q1 + q2 + 2 * final) / 400.00 ) * 0.55 //integer division here can cause hard to find problems
ex: q1 = 50; q2 = 50; final = 50 -> (200/400.00) * 0.55 = 0.275

For the lab and project component make a similar calculation.
each of the 14 labs are worth 5 points for 70 points total
the projects will be worth 140 points
workScores = ((labTotal + projectTotal) / 210.00 ) * 0.45
ex: labTotal = 35, projectTotal = 70 -> (105/210) * 0.45 = 0.225

add these two scores together and multiply by 100 to get a number between 0 and 100
ex: (0.275 + 0.225) * 100 = 50 percent

letterGrade:
The member function letterGrade(double avg) should compute the letter grade based on the weighted average and return this value as a char.

90 - 100 -> A
80 -  89 -> B
70 -  79 -> C
60 -  69 -> D
59 -   0 -> F

assume the program has declared four objects (s1, s2, s3, s4) and initialized them as follows.
s1 - using the default constructor
s2 - using the 3 arg constructor with (4321, "Kelly", "Jones")
s3 - using the 8 arg constructor with (8712, "Jade", "Stone", 82, 72, 94, 68, 126)
s4 - using the 8 arg constructor with (2379, "Ryan", "Wong", 82, 74, 73, 55, 102)

Enter data for student number 1
Enter Id number, First name, and Last Name: 8322 Audrey Brill
Enter scores for mid1, mid2, final, labs, projects: 76 76 82 58 90
Enter data for student number 2
Enter quiz1, quiz2, final, lab total, project total 88 81 78 55 80

NOTES:

• The project is to be broken up into three files: A ".h" file with the class definition (interface), a file ".cpp" that implements the class, and a main cpp program that serves as a driver to test the CS150Student Class.
• This class will be used for the final project. It is therefore very important that the class works as specified and has been thoroughly tested.
• STYLE NOTE: Include pre- and post-conditions for each of the member functions in the .h file. Be sure to include function headers for each function in the .cpp file.

Phase 2 (10 Points)

For phase two you will need to declare an array to hold CS150Student objects. The array will be filled by reading values from a file. Override the extraction (>>) and the insertion (<<) operators and then use them when reading from the file and sending output to the screen.. You must also make Correct use of the const modifier. Once the records are read from the file, print a report containing all data from the file as well as the average and letter grade for each student. See sample dialog below (user input in bold).

enter file name: data.txt

idNum          name     mid1  mid2  final  labs  proj  average  grade
 6789     Robert Smith    62    69     72    60    72    66.10    D
 5557        Bob Smith    92    82     84    65    92    80.67    B
 6783       Jill Kelly    62    49     62    60    65    59.10    F

Phase Two NOTES:

• The project is to be broken up into three files as noted above:
• you must override the extraction operator and use it to read data from the file
• you must override the insertion operator and use it to print the report
• use must use the const modifier where applicable
• you must format the output to line up in columns
• use 2 decimal point precision
• use functions - this will make your code easier to use for the other phases

Phase 3 (10 Points)

For phase three, the user will be able to perform various operations on the student data, through a menu-driven interface. There should be a menu option for each of the following:

• populate the array with data from a file (user enters name)
• display a report of all students (formatted as shown above)
• display a students data knowing the id number (user enters id number)
• exit the program

Phase Three NOTES:

• as above
• Program loops until user chooses to exit.
• allow upper and lower case choices

---

Phase 4 (20 Points)

Add the following functionality to the program and add them as menu choices menu.

• add a student to the list
• delete a student (based on id number)
• update a student score(based on id number)
• display all students sorted by their id numbers
• add #ifndef, #define, #endif directives to your header file

Phase Four NOTES:

• as above
