Question

create a C++ program using Visual Studio that could be used by a college to track its courses. In this program, create a CollegeCourse class includes fields representing department, course number, credit hours, and tuition. Create a child (sub class) class named LabCourse, that inherits all fields from the the CollegeCourse class, includes one more field that holds a lab fee charged in addition to the tuition. Create appropriate functions for these classes, and write a main() function that instantiates and uses objects of each class. Save the file as Courses.cpp. Compile this application using Visual Studio and run it to make sure it is error free. Please attach your project folder in a zipfile when submitting. GRADING RUBRIC: - define a class named CollegeCourse - private fields for department, course number, credit hours, and tuition - public function(s) setting the private fields - public function that displays a CollegeCourse's data - define a class named LabCourse - inherit from CollegeCourse - include field that holds a lab fee - public function(s) setting the private field (don't forget the parent) - public function that displays a LabCourse's data (don't forget the parent) - main() function that instantiates a LabCourse, populates all private and inherited fields, calls both private and inherited methods
