1) Properties required for a course are : number (used to identify a course by a unique number), title (name of the course), description (brief details of the course) and credits (number of credit points the completion of course will provide).
2) Deplartment class has a overridden toString() method, which is internally returning the name of the department. Because of this, the department name is being displayed.
3) Data type stored in department combobox of the Courses Form will be a department prefix string. This is because in both the ways of adding a department, we need to always provide department prefix and the same is being used intoString method, which will be called to store the value of a department.
4) Use of FOR loop here is to iterate over all the courses and get the total credit that will be offered on coletion of these courses.
5) Course Department property in a course does not need validation bacause the department of all the courses are fixed and final, and will not need any validation.
6) CourseID is a combination of course name and course number. Here this combination is used so that is always unique for each course.
7) Consider Department.cs file, it has 2 overloaded contructors. Both of these overloaded contructors differ by number of arguments.
8) Use of if condition here is to check if the course that we are trying to add already exists ot not. If it already exists and we try to add the same course again, then this if condition will detect that and throw a Invalid Course exception.
