The objective of this assignment is to demonstrate an ability to implement inheritance, composition, and overloaded operators in a program. This program leverages many of the concepts that you have learned in this class and combines them into a professional-style program.
Classes are getting to be more realistic with each programming assignment. This assignment includes the valuable aspect of inheritance to facilitate reuse of code and operator overloading to allow the usage of familiar operators tailored specifically to the Person, Student, and Faculty classes. Composition is also demonstrated in the use of a Course class that contains objects of the Student and Faculty classes.
You are working in the IT department for a university and have been tasked with developing an application that will manage the registration process, which involves the creation of a course, the enrollment of students in the course, and the assignment of faculty members to teach the course.
You will need to create several classes to maintain this information:
Course, Person, Student, Faculty, and Date.
The characteristics of Students and Faculty are shown below:
| Students: | Faculty: |
| ID (string) | ID (string) |
| First Name (string) | First Name (string) |
| Last Name (string) | Last Name (string) |
| Birthdate (Date) | Birthdate (Date) |
| Date enrolled (Date) | Date hired (Date) |
| Major (string) | Title (string) |
| Level (string) (i.e. Freshman, Sophomore...) | Rank (string) |
| GPA (double) | Salary (double) |
Several of the data members above require the use of dates. Strings will not be acceptable substitutes for date fields.
C++ does not have a built in data type for Date. Therefore, you may use this Date class in your program:
#pragma once
#include < iostream >
#include < cstdlib >
#include < cctype >
class Date{
friend std::ostream& operator<<(std::ostream&, Date);
public:
Date(int d=0, int m=0, int yyyy=0)
{
setDate(d, m, yyyy);
}
~Date() {}
void setDate(int d, int m, int yyyy){
day = d;
month = m;
year = yyyy;
}
private:
int day;
int month;
int year;
};
std::ostream& operator<<(std::ostream& output, Date d){
output << d.month << "/" << d.day << "/" << d.year;
return output;
}
The Person class should contain data members that are common to both Students and Faculty.
Write appropriate member functions to store and retrieve information in the member variables above. Be sure to include a constructor and destructor.
Both the Student and Faculty classes should be derived from the Person class. Each should have the member variables shown above that are unique to each class. The data members that are common to both classes should be inherited from the Person class.
In each derived class, the << operator should be overloaded to output, neatly formatted, all of the information associated with a student or faculty member.
The < operator should be overloaded in the Student class to enable sorting of the vector of Student objects that will exist in the Course class. You will use the sort function to sort this vector. The sort function is part of the < algorithm > library.
Write member functions to store and retrieve information in the appropriate member variables. Be sure to include a constructor and destructor in each derived class.
The Course class has a name data member (i.e. a course's name might be "MIT 112").
The class contains a Faculty object that represents the Faculty member assigned to teach the class.
The class contains a vector of Student objects that represent the students enrolled in the class.
The class has an integer variable, capacity, that represents the maximum number of students that can be enrolled in the class.
The Course class should support operations to assign a faculty member to the course, enroll students in the course, and list all of the course information, including its name, capacity, instructor, and students enrolled in it.
You should write a main() function that begins by prompting the user for the name and capacity of a course:
Enter a name for your Course: MIT 112
What is the maximum capacity for your Course? 24
It should then present a menu to the user that looks like this:
Main Menu
I -- Add Instructor
S -- Add Student
L -- List Course Information
Q -- Quit
Selection:
"S" should allow the user to create a Student record and enroll the Student in the Course. Likewise, I should allow the user to create an Instructor (aka Faculty) record and assign the Faculty member to the course as the instructor. L should list ALL of the course information, including all of the information about the Students assigned to the course, (sorted by ID number), as well as all of the information about the faculty member assigned to teach the course. The user should be able to create and assign only ONE faculty member to teach the course, but create and enroll as many Students to the course as the capacity allows. The user should be able to list repeatedly until he or she selects Q to quit.
Below are some examples of the information that needs to be entered by the user:
Create and assign a faculty member as the instructor:
Create Faculty Member
ID: 12345
First Name: Melesa
Last Name: Poole
Birthdate (mm/dd/yyyy): 01/20/1900
Title: Dr.
Rank: Associate Professor
Salary: 1000000000
Date of Hire: 06/26/2009
Result of listing Course Information before assigning any students to the course:
Information for Course MIT 112
Instructor:
Faculty ID: 12345
Faculty Name: Dr. Melesa Poole, Associate Professor
Birth Date: 1/20/1900
Date Hired: 6/26/2009
Salary: 1000000000.00
No students are enrolled in the course.
Create and assign a student to the course:
Create Student
ID: 11111
First Name: John
Last Name: Smith
Birthdate (mm/dd/yyyy): 05/05/1995
Major: Accounting
Level (Freshman, Sophomore, Junior, Senior): Junior
GPA: 3.95
Date of Enrollment: 12/12/2020
List of Course Information after assigning two students:
Information for Course MIT 112
Instructor:
Faculty ID: 12345
Faculty Name: Dr. Melesa Poole, Associate Professor
Birth Date: 1/20/1900
Date Hired: 6/26/2009
Salary: 1000000000.00
These are the Students enrolled in the MIT 112 course:
Student ID: 11111
Student Name: John Smith
Birth Date: 5/5/1995
Date Enrolled: 12/12/2020
Major: Accounting
Level: Junior
GPA: 3.95
Student ID: 22222
Student Name: Jane Doe
Birth Date: 6/22/1997
Date Enrolled: 1/1/2020
Major: Computer Science
Level: Sophomore
GPA: 3.45
[Notice that the Students are sorted by IDs in the output above.]
Output if neither students nor an instructor has been assigned to the course:
Information for Course MIT 112
No instructor has been assigned to the course.
No students are enrolled in the course.
Output if Students have been enrolled but no instructor has been assigned:
Information for Course MIT 112
No instructor has been assigned to the course.
These are the Students enrolled in the MIT 112 course:
Student ID: 11111
Student Name: John Smith
Birth Date: 5/5/1995
Date Enrolled: 12/12/2020
Major: Accounting
Level: Junior
GPA: 3.95
Output if the class is full and the user tries to add another student:
The class is full. No more students can be added.
There are several things to point out about the output:
1. For each Student, the first name and last name are output on the same line, separated by a space.
2. For the instructor, the format should be this: title [space] first name [space] last name [comma] rank
3. All of the data should line up in neat columns as shown above.
