Objectives

After this homework assignment, students should be able to:

 Implement user-defined structs using given specifications

Use file input to populate structs

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

- T 10 05 AM 110 Lab

- W 9 05 AM 50 Lecture

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 and courses.

Instructions

Write a C++ program named lionpath.cpp that implements the structs described below:

Student

The Student struct contains basic identifying information about one student and a vector of courses that the student is scheduled to take:

Attribute Data Type

First name string

Middle initial char

Last name string

9-digit PSU ID Number string

PSU Username string

Enrolled Courses vector<Course>

Course

The Course struct contains the following information:

Attribute Data Type

Course name string

Number of lectures per week int

-------------------------------------------------------------------

Write a main function that:

 Reads a text file (like shown in the background)

 Automatically populates a Student struct with relevant information

 Displays a simplified version of it to the console window

Note that only the number of lectures per course needs to be counted, which means the content of the lines

containing information about each lecture can be ignored.

Optional Bonus (+2 points)

Write a C++ program named schoolday.cpp that extends the functionality lionpath.cpp by:

 Accepting user input for a character representing a weekday:

o M, T, W, R, or F

 Printing information about all lectures scheduled on that day
