Create a class named Instructor. It contains a first and last name and an office
number, and its only constructor requires all three as arguments. Create a class named
Classroom. It contains a building and a room number, and its only constructor requires
both as arguments. Create a class named CollegeCourse. A CollegeCourse contains
an Instructor, a Classroom, and a number of credits. Its constructor requires a first
and last name of an instructor, the instructor’s office number, a Classroom building
and room number, and a number of credits. Each of these classes contains a function
that displays an object’s values. Write a main()function that instantiates at least two
CollegeCourse objects and displays their values. Save the file as CollegeCourse.cpp.
