Design the class doctorType, inherited from the class personType with an additional data member to store a doctor’s speciality. Add appropriate constructors and member functions to initialize, access, and manipulate the data members and this class should implement abstract method of class PersonType. c) Design the class billType with data members to store a patient’s ID and a patient’s hospital charges, such as pharmacy charges for medicine, doctor’s fee, and room charges. Add appropriate constructors and member functions to initialize and access and manipulate the data members.

OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Question
- Write a program to computerize the billing system of a hospital.
- a) Design the personType class as shown below:
PersonTye |
-firstname: String -lastname: String |
+print(): void +setNAme(string, string) : void +getFirstName() : string +getLastName() : string +abstract personType(): string |
- b) Design the class doctorType, inherited from the class personType with an additional data member to store a doctor’s speciality. Add appropriate constructors and member functions to initialize, access, and manipulate the data members and this class should implement abstract method of class PersonType.
- c) Design the class billType with data members to store a patient’s ID and a patient’s hospital charges, such as pharmacy charges for medicine, doctor’s fee, and room charges. Add appropriate constructors and member functions to initialize and access and manipulate the data members.
- d) Design the class patientType, inherited from the class personType with additional data members to store a patient’s ID, age, date of birth, attending physician’s name, the date when the patient was admitted in the hospital, and the date when the patient was discharged from the hospital. Add appropriate constructors and member functions to initialize, access, and manipulate the data members. Write a program to test your classes.
- A company plans to create a system for managing of a movie store. The movie store has a name, address and phone number. Movies are described with title , genre, year of creation, number of sold copies and list of songs. The songs are described with name and duration. Design a set of classes and relationship between each other, which models the data of the record company. Implement a test class, which demonstrates the work of rest of the classes.
