- Implement the Seller class as a derived class of Person class. Create the seller.h and seller.cppfiles for this class. The Seller class contains additional data members that hold a seller’s:o average star rating received from the buyers, ando total number of items sold.These data should be accessible by its derived classes. (should these data be private, public, orprotected?) The following methods are included in the seller class:• A default constructor and a copy constructor• A constructor that receives all of the data for a seller.(for the constructors, make sure to call the base class constructor as appropriate)• Appropriate get and set functions for the new data in this class• print() – overrides the base class print() to print the base class data and print all additionalseller data with appropriate messages. Make sure to call the base class print to print thebase class data.• read() – overrides the base class read() to read the base class data and reads all additionalseller data…Create an abstract super class called Employee with the following attributes: Use JavaDoc comments in the Parent and Child Classes only but use @author for the driver name : String and the following methods getter and setter for the one attribute two constructors an abstract method called getPay() equals() toString() Create a sub class of Employee called SalaryEmployee with the following attribute yearlyPay : double and the following methods getter and setter for the one attribute two constructors getPay() that returns the yearlyPay divided by 52 equals() toString() Create a sub class of Employee called HourlyEmployee with the following attributes: hoursWorked : double payrate : double and the following methods getters and setters for the two attributes two constructors getPay() that returns the weekly pay (multiply hoursWorked by payrate - overtime included and 1.5 times payrate for hours > 40) equals() toString() Create a sub class of Employee called SalesEmployee with the…Write a class Distance which has two private data members (int feet,float inches). The class has three constructors which are having no parameter - values of both feet and inches are assigned zero. having two numbers as parameters - the two numbers are assigned as feet and inches respectively. having one number as parameter - both feet and inches are assigned that number. Provide getters and setters for data members. Now write a main class which demonstrate the functionality of above class by calling all constructors, setters & getters. Create 1 object using default constructor, and use setters to set values, then getters to print values. Create a second object using constructor having two parameters, provide values, then print values on screen. Create third object by using third constructor having one parameter, after that print values on screen.
- Consider a base class Employeewhich contain basic information of an employee such as: Name(string) Address(string) Id(int) Gender(string) Now create two constructors A default constructor to initialize the data member with default values, A four-argument constructor to initialize data field with user-define values ( must use this key word). Getter and setter function to set and get values of data fields. Derives two classes to show Hierarchical inheritance. A departmentclass which extends the base class employee also have some its own information such as: Department Name(string) Department Id(int). Now create two constructors a default constructor to initialize the data member with default values, a parameterized constructorto initialize data field with user-define values. Appropriate getter and setter function to set and get values of data fields. A display method to show all the records of employee along with department information. Create another child class Loanwhich extends the…Consider a base class named Employee and its derived classes HourlyEmployee and PermanentEmployee while taking into account the following criteria.• Employee class has two data fields i.e. a name (of type string) and specific empID (of type integer)• Both classes (HourlyEmployee and PermanentEmployee) have an attribute named hourlyIncome• Both classes (HourlyEmployee and PermanentEmployee) have three-argumentconstructor to initialize the hourlyIncome as well as data fields of the base class• Class HourlyEmployee has a function named calculate_the_hourly_income to calculate the income of an employee for the actual number of hours he or she worked. One hour income is Rs. 150 • Similarly, PermanentEmployee class has function named calculate_the_income to calculate the income of an employee that gets paid the salary for exact 240 hours, no matter how many actual hours he or she worked. Again, one hour salary is Rs. 150.Implement all class definitions with their respective constructors to…Q3 Use the concept of polymorphism and classes to represent the following analog A Transportation class has the fields (model, year) with all the setters and getters. An Airplane class inherits Transportation, and it has a field number of wings (no wings) with a setter and a getter. A Car class inherits Transportation, and it has a field number of wheels (no wheels) with a setter and a getter. Al the parent and child classes have toString( ) method that prints everything. In the main program, create an array of transportations of size 6 (3 of them are airplanes and 3 are cars), and put any values you choose in the constructors. Finally run a loop through the array and print all the information, and by using the tool “instance of” if the element is an airplane, print “BINGO..AIRPLANE”, if the element is a car, print “BINGO..CAR”
- Give a definition for a class SmartBut that is a derived class of the base classSmart given in the following. Do not bother with #include directives ornamespace details.class Smart{public:Smart( );void printAnswer( ) const;protected:int a;int b;};This class should have an additional data field, crazy, of type bool; oneadditional member function that takes no arguments and returns a value of type bool; and suitable constructors. The new function is named isCrazy. You do not need to give any implementations, just the class definition.Consider a base class Employee which contain basic information of an employee such as:Name(string)Address(string)Id(int)Gender(string)Now create two constructors A default constructor to initialize the data member with default values, A four-argument constructor to initialize data field with user-define values ( must use this key word). Getter and setter function to set and get values of data fields.Derives two classes to show Hierarchical inheritance.A department class which extends the base class employee also have some its own information such as:Department Name(string)Department Id(int).Now create two constructors a default constructor to initialize the data member with default values, a parameterized constructor to initialize data field with user-define values.
