In assignment you are required extend the Patient class to implement an  Inpatient  class,  representing a patient who is admitted to the hospital for a longer term and who may require multiple procedures to be performed.

An Inpatient is placed under observation after a procedure has been performed until the supervising doctor is satisfied that their recovery has progressed well enough to either perform the next scheduled procedure (if any are remaining) or to discharge the patient.

Additional functionality for dealing with multiple  procedures and the new state "O"(under observation), and overridden versions of methods defined in the  Patient class, will need to be implemented (which introduce additional conditions for some state transitions).

In the second part (of this assignment) you are also required to develop a menu-driven application where both Patient and Inpatient objects are stored in a common array, which must be manipulated in a polymorphic way when appropriate.
