Chapter 19, Problem 19.6E

(Student Inheritance Hierarchy) Draw an inheritance hierarchy for students at a university similar to the hierarchy shown in Fig19.2. Use Student as the base class of the hierarchy, then include classes UndergraduateStudent and GraduateStudent that derive from Student. Continue to extend the hierarchy as deep (i.e., as many levels) as possible. For example, Freshman, Sophomore, Junior and Senior might derive from UndergraduateStudent, and DoctoralStudent and Masters Student might derive from GraduateStudent. After drawing the hierarchy, discuss the relationships that exist between the classes. [Note: You do not need to write any code for this exercise.]
