Hello all, I am trying to finish this program, but am running into some trouble with the main() (I think).
It will output the courseID, but no grade, points, honorPoints, or averages
I think that I have everything overloaded correctly, but am messing up with the array of objects part of it, Am I completely off base here?
any advice or suggestions would be great. Here is directions for the part I am messing up.
Overload the +operator() so that honor points for courses can be summed to create a summary CollegeCourse object.
Overload the /operator() so that a CollegeCourse object's honorPoints can be divided by an integer; this function should also return a double.
Overload the <<operator() to display the details of a CollegeCourse.
Write a main() program that declares CollegeCourse objects.
Instantiate your CollegeCourse objects by creating an array of objects.
Show your CollegeCourses using the +operator() and /operator() to compute the average honorPoints for the CollegeCourses.
