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…
Given the following class declaration (with prototypes): class Carpet { private: double pricePerSqYd; public: Carpet(); void setPricePerYd(double p); void setDimensions(double l, double w); double getTotalPrice() const; }; Assume the class Carpet has been implemented. Assume the class Rectangle has been implemented. Rewrite the entire Carpet class declaration and add a member variable named size which is an instance of the Rectangle class.
Given the following class definition: class employee{public: employee(); employee(string, int, double); employee(int, double); employee(string); void setData(string, int, double); void print() const; void updatePay(double); int getNumOfServiceYears() const; double getPay() const;private: string name; int numOfServiceYears; double pay;}; Create a class parttime derived from the above class that includes private members payRate and hoursWorked of type double along with a constructor and the definition of a print function that prints out all information from the base and derived class. Provide a test program that would demonstrate the working parttime class. Note: You can assume all code is stored in a single file.

Q1) Write the Code the following scenario. Write an abstract function named receivePay in interface with return type double and no parameters. Write another incomplete function, name Show with return type void and an argument of type int in that interface. Build a class with name Bill that implements the above interface. Bill class with name BillId , itemsquantity and itemsprice with proper datatypes with private access . Define two constructors,one default and other is parameterized to initialize the class members . Now receivePay has to beimplemented in such a way that its displays product of itemsquantity and itemsprice and Display function will display the BillId.Can we do same task with abstract class instead of interface?

Build a class Pet having the following data membersa. Name (String)b. Gender (char)c. Type (String)d. Age (int)e. Weight (float)f. healthCondition (int)Imagine this class Pet represents your pet as a virtualobject. Provide constructors with arguments for name,gender, type, age and weight. Initialize healthCondition to 5(which means healthy). Provide getter for each of these but setter for only weight. Provide a function eat(String food). This function represents the action of eating thatwould increase the weight of the pet according to following rulesFood Increase In WeightRed Meat 0.14 kgChicken 0.12 kgPet Food 0.17 kgSupplement 0.1 kgFish 0.09 kgThe eat function returns the new Weight of the pet object.Provide another function fallSick() that reduces the healthCondition of the pet 1 but it cannot gobelow 0. Provide a function bool isDead() this function returns true if the healthCondition of a pet is 0and false otherwise. Add another function recover().
