You are hired as a contractor to help a university migrate an existing student system to a new platform using C++ language. Since the application already exists, its requirements exist as well, and they are outlined in the next section. You are responsible for implementing the part of the system based on these requirements. A list of data is provided as part of these requirements. This part of the system is responsible for reading and manipulating the provided data.
You must write a program containing five classes (i.e., Student , SecurityStudent , NetworkStudent , SoftwareStudent , and Roster ). The program will maintain a current roster of students within a given course. Student data for the program includes student ID, first name, last name, email address, age, an array of the number of days to complete each course, and degree. This information can be found in the studentData table below. The program will read a list of five students and use function calls to manipulate data (see part F4 in the requirements below). While parsing the list of data, the program should create student objects using the appropriate subclasses indicated by the degree program. The entire student list will be stored in one array of students called classRosterArray Specific data-related output will be directed to the console.
STUDENT DATA TABLE
A4 Erin Black Erin.black@comcast.net 22 50, 58, 40 SECURITY
A5 [Your first name Your last name] [Your valid email address] [Your ag]e [Number of days to complete 3 courses] SOFTWARE
The data should be input as follows:
const string studentData[] = {"A1,John,Smith,John1989@gm ail.com,20,30,35,40,SECURITY", "A2,Suzan,Erickson,Erickson_1990@gmailcom,19,50,30,40,NETWORK", "A3,Jack,Napoli,The_lawyer99yahoo.com,19,20,40,33,SOFTWARE", "A4,Erin,Black,Erin.black@comcast.net,22,50,58,40,SECURITY", "A5,[firstname],[lastname],[emailaddress],[age], [numberofdaystocomplete3courses],SOFTWARE"
Create a program that converts the array of strings found in the studentData table to an array of student objects by doing the following:
A. Modify the studentData table to include your personal information as the last item.
B. Create a C++ project in your integrated development environment (IDE) with the following files:
• degree.h
• student.h and student.cpp
• networkStudent.h and networkStudent.cpp
• securityStudent.h and securityStudent.cpp
• softwareStudent.h and softwareStudent.cpp
• roster.h and roster.cpp
Note: There must be a total of 11 source code files.
C. Define an enumerated data type Degree for the degree programs containing the following data elements SECURITY, NETWORKING and SOFTWARE.
Note: This information should be included in the degree.h file.
D. For the Student class, do the following:
- Create the base class Student in the files student.h and student.cpp, which includes each of the following variables:
• student ID
• first name
• last name
• email address
• age
• array of number of days to complete each course
• degree types
Note: Degree type should be populated in subclasses only.
-
Create each of the following functions in the Student class:
a. an accessor (i.e., getter) for each instance variable from part D1 b. a mutator (i.e., setter) for each instance variable from part D1 c. constructor using all of the input parameters provided in the table d. virtual print() to print specific student data e. destructor f. virtual getDegreeProgram()
Note: All access and changes to the instance variables of the Student class should be done through the accessor and mutator functions.
Note: Leave the implementation of the getDegreeProgram() function empty.
- Create the three following classes as subclasses of Student, using the files created in part B:
• SecurityStudent
• NetworkStudent
• SoftwareStudent
Each subclass should override the getDegreeProgram() function. Each subclass should have a data member to hold the enumerated type for the degree program using the types defined in part C.
E. Create a Roster class (roster.cpp) by doing the following:
1. Create an array of pointers, classRosterArray, to hold the data provided in the studentData table.
2. Create a student object for each student in the data table by using the subclasses NetworkStudent, SecurityStudent, and SoftwareStudent, and populate classRosterArray.
a. Apply pointer operations when parsing each set of data identified in the studentData table.
b. Add each student object to classRosterArray.
3. Define the following functions:
a. public void add(string studentID, string firstName, string lastName, string emailAddress, int age, int daysInCourse1, int daysInCourse2, int daysInCourse3, < degree program >) that sets the instance variables from part D1 and updates the roster.
b. public void remove(string studentID) that removes students from the roster by student ID. If the student ID does not exist, the function prints an error message indicating that the student was not found.
c. public void printAll() that prints a complete tab-separated list of student data using accessor functions with the provided format: 1 [tab] First Name: John [tab] Last Name: Smith [tab] Age: 20 [tab]daysInCourse: {35, 40, 55} Degree Program: Security. The printAll() function should loop through all the students in classRosterArray and call the print() function for each student.
d. public void printDaysInCourse(string studentID) that correctly prints a student’s average number of days in the three courses. The student is identified by the studentID parameter.
e. public void printInvalidEmails() that verifies student email addresses and displays all invalid email addresses to the user
Note: A valid email should include an at sign ('@') and period ('.') and should not include a space (' ').
f. public void printByDegreeProgram(int degreeProgram) that prints out student information for a degree program specified by an enumerated type
F. Demonstrate the program’s required functionality by adding a void main() function to roster.cpp, which will contain the required function calls to achieve the following results:
1. Print out to the screen, via your application, the course title, the programming language used, your student ID, and your name.
2. Create an instance of the Roster class called classRoster.
3. Add each student to classRoster.
4. Convert the following pseudo code to complete the rest of the main() function:
classRoster.printAll();
classRoster.printInvalidEmails();
//loop through classRosterArray and for each element:
classRoster.printAverageDaysInCourse(/*current_object's student id*/);
classRoster.printByDegreeProgram(SOFTWARE);
classRoster.remove("A3");
classRoster.remove("A3");
//expected: the above line should print a message saying such a student with this ID was not found.
5. Call the destructor to release the Roster memory.
