1. Design and implement a class named "Patient" using The class should store patient name, patient age, telephone number of patient, doctor name last visited, and diagnosis of last visit. The class has two member functions:

• First to input data values into all the data members of an object.

• Second to display information stored in an object.

Write appropriate main( function that creates a list of five "Patient" objects in an array. The main( function should include a code that inputs information in the objects using member function and also for displaying information of all the objects using data members.

2. Consider the following class hierarchy along with suggested data members:

Design and implement the classes in the hierarchy using You may add more data members in the classes, if needed. You should include at least one constructor in each class. All the classes should have a member function print_item_info() which should display all the data of the object. You must demonstrate polymorphism using print_item_info() and main() functions.
