Question

Write a program that will manage your school course schedule. The program should allow you to enter a list of your courses and have them saved in a file. It should also allow you to read a previously created course list from a file and display it on the screen. The course information should include: Course code and name, meeting day and time, building, room number, and instructor. The program should allow the user to make repeated requests until they choose to exit. The program should have an option to print out a list that just includes Course code, Meeting day/time, Building, and Room number. The program should use at least two struct types and one enumerated type.

Explanation / Answer

#include <iostream>
#include <fstream>
#include <string>
#include <list>
#include <stdlib.h>
using namespace std;

/*
* Programme functions:
* 1. Enter the list of courses
* 2. Save the list of courses to a file.
* 3. Read a previously created course list from a file.
* 4. Display the list containing course code, Meeting day/time, Building, and Room number.
* 5. Option to exit the programme.
* Course details to capture: Course code, course name, meeting day/time, building, room number, instructor name.
