CMPSC121: Intro to Programming Techniques (Fall 2018)

Project 3 (100 points)

Due Friday, December 7 at 11:59pm

Objectives

After this project, students should be able to:

Implement user-defined classes using given specifications, including

o Member variables

o Member functions

o Constructors

Use file input and output to save results

Background

While working to improve the LionPath website, you discovered a way to generate formatted text files that

contains information about students' schedules for the upcoming semester. Consider the example below:

FNAME: Andrew

MINIT: S

LNAME: Yu

ID: 912345678

USER: auy77

CMPSC121-002-003L

- M 9 05 AM 50 Lecture

- W 9 05 AM 50 Lecture

- T 10 05 AM 110 Lab

MATH140-001

- M 12 25 PM 50 Lecture

- T 12 25 PM 50 Lecture

- W 12 25 PM 50 Lecture

- R 12 25 PM 50 Lecture

PSU007-001

- W 06 00 PM 50 Lecture

ENGL101-004

- M 11 15 AM 50 Lecture

- W 11 15 AM 50 Lecture

- F 11 15 AM 50 Lecture

PHYS211-003-006L

- T 3 35 PM 90 Lecture

- R 3 35 PM 90 Lecture

- F 12 00 PM 110 Lab

Each line that begins with "-" refers to one of the meeting times of the course above. For example:

- M 9 05 AM 50 Lecture Monday, 9:05AM, 50 minute lecture

Because LionPath can generate many of these files, you have decided to write a C++ program that can

automatically process them. You will use object-oriented programming to keep track of the students, the

courses, and the lecture times.

Instructions

Implement the classes described below:

Student

The Student class contains basic identifying information about one student:

First name

Middle initial

Last name

9-digit PSU ID Number

PSU Username

In addition, it contains a list of courses that the student is scheduled to take. Certain actions related to the

student can be taken:

Add a course

Remove a course

Print information about all courses (to console window and/or file)

Check whether the student will be available (not in class) at a certain time and day of the week

Check whether the student is available right now

Course

The Course class contains minimal information:

Name of the course

It also contains a list of meeting times (labs and lectures). There is only one action related to the course:

Print information about all meeting times (to console window and/or file)

Lectures

The Lecture class contains all the information about one meeting time (lab or lecture) for a course, of which

there may be many:

Day of the week

Starting time

Duration

Whether it is a lab or lecture session

There is only one action related to the course:

Print information about the meeting time (to console window and/or file)

You are required to implement but are NOT limited to the member variables and functions described above.

You may find it beneficial to implement additional classes, member functions, and member variables that suit

your needs.

Main Function

In the main function, provide the user with 6 options:

1. Select student by ID

The user is prompted to enter a PSU ID Number

o If a corresponding file (e.g. "912345678.txt") exists, then open it

Create a new student object containing all the provided information

If there are pre-existing scheduling conflicts, then remove one of the courses

o If not, then allow the user to create a new student object with that number

Prompt the user for the student's name and username

Options 2-5 should not be available until the user selects a student

2. Modify schedule

Delete an existing course (provide a list of course names to choose from)

Add a new course

o Use user input to populate the course name and meeting times

o If there is a scheduling conflict with an existing course:

Display the course and meeting time with which it conflicts

Do not add the new course

3. Check student availability

Determine whether the student should be in class right now

o Use functions defined in the <ctime> library to get the current time

Determine whether the student will be in class at a certain time and day of the week

If the student is/will be in class, then display the course and meeting time

4. Display Schedule

Generate and print all the information in the same format as the given text file

5. Write to file

Generate and save all the information in the same format as the given text file

Overwrite the existing file (if it exists)

6. Quit

If the student's schedule has been modified but not written to file, give the user a warning

o The user may quit anyways, losing any unsaved changes

o The user may return to the menu
