Using the codes below. in C++

Use three files ( .cpp, .h and main )

a) Implement a main program that prompts the user and prints the classes you are taking this trimester. Use a dynamic array and functions with arguments of the Course class.

b) Modify the Course, Instructor, and TextBook classes by adding attributes and member functions, described last.

c) Add the >>, << operators in each class. (ostream and istream)
