Question

I need help on this home work:

Using OOP, write a C++ program that will read an input file to manage a list of students waiting to register for a course using a linked list.

The input file name is WaitList.txt and is located in the current directory of the project.

Waitlist.txt content:

1 Samuel Stone
1 Brett Bacher
2 Emily Evans
4
4
3
3
1 Zachary Zillings
2 Carson Cummings
1 Penny Plumber
3
1 Tammy Thompson

The file layout is as follows:

action student name

Actions are defined as follows:

1 - add student name to the end of the linked list
2 - add student name to the beginning of the linked list
3 - delete the student at the beginning of the linked list
4 - delete the student at the end of the linked list

Actions #1 and #2 require student names. Actions #3 and #4 do not.

For example, if the input file contents contained:

1    Sally Sue Student
1    Peter Pupil
1    Sam Scholar
4
2    Terri Flowers
1    Abby Achiever
3
2    Bill Brain

The program would display the wait list as follows:

The Wait List:

1. Bill Brain
2. Sally Sue Student
3. Peter Pupil
4. Abby Achiever

End of List.

Then the program will prompt the user if they wish to delete a student by name. If the user selects 'y', the program will prompt for a student name.
If the name is found in the linked list, the student node will be deleted and the wait list is then displayed. If the name is not found, an error message is displayed to the user.

If the user selects 'n' to deleting a student by name, the program will end.

The Wait List:

1. Bill Brain
2. Sally Sue Student
3. Peter Pupil
4. Abby Achiever

End of List.

Would you like to delete a student by name (y = yes, n = no): Y
Enter the full name of the student to delete: peter pupil

Student deleted.

The Wait List:

1. Bill Brain
2. Sally Sue Student
3. Abby Achiever

End of List.

Would you like to delete a student by name (y = yes, n = no): y
Enter the full name of the student to delete: casey clever

Student does not exist on the wait list.

The Wait List:

1. Bill Brain
2. Sally Sue Student
3. Abby Achiever

End of List.

Would you like to delete a student by name (y = yes, n = no): a
Invalid response, please enter y = yes, n = no: n

Program end.

Validate all user input values, and use good programming methodology and keep your project modular.

Use private member functions and variables.
Use public member functions for a constructor (where appropriate) and a driver method only.

These specifications do not give a list of method names to be used. It is assumed the program will use several methods doing one task each.

NOTE: Any submission that uses global variables or does not use a class and object appropriately will result in a project grade of 0.
