Person and Customer Classes Write a class named (Person) with data attributes for a person’s name, address, and telephone number. Provide accessors/getters and mutators/setters for each attribute. Write a displayPerson() to print out the attributes of the Person. Next, write a class named (Customer) that is a subclass of the (Person) class. The (Customer) class should have a data attribute for a customer number, and a Boolean data attribute indicating whether the customer wishes to be on a mailing list. Provide accessors/getters and mutators/setters for each attribute. Write a display customer() to print out the attributes of the Customer. Demonstrate an instance of the (Customer) class in a simple program.
Create abstract class Pet , which is the abstract superclass of all animals. Declare a integer attribute called legs, which records the number of legs for this animal. Define a constructor that initializes the legs attribute. Declare an abstract method eat. Declare a concrete method walk that prints out something about how the animals walks (include the number of legs). Create the Dog class. The Dog class extends the Pet class. This class must include a String attribute to store the name and food of the pet Define a default constructor that calls the superclass constructor to specify that all dogs have 4 legs and name. override the eat and walk method. Create the Cat class that extends Pet. This class must include a String attribute to store the name of the pet, and a string to save food . Define a constructor that takes one String parameter that specifies the cat's name and food. This constructor must also call the superclass constructor to specify that all cats have four legs.…

Scenario:You are hired by a game development company. Your task is to create an RPG hack & slash console game. The game will have a movement system that will be based on the x, y, z coordinate system. You will need to start with creating 3 classes.1. A class that represents a player2. A class that represents an enemy3. An abstract class that contains the movement logic.Step 1:Start by creating the superclass which defines the movement system for both enemy and player. The movement system is based on the Coordinate system. Imagine an x, y, z plane, the y coordinate is used to move forward and backward in the virtual plane, x to go left and right, z to go up and down.For example, A player with coordinates x, y, z with values -5, 10, 0 represents a player -5 units to the left, 10 units forward, and 0 z units mean on the ground. (0, 0, 0) are the base units which means the player or enemy is at the start of the level.Step 2:Create a class to represent the player which is derived from…
Create an abstract CardGame which contains a “deck” of 52 playing cards that uses a Card class that holds a suit and value for each Card object. It also contains an integer field that holds the number of cards dealt to a player in a particular game. The class contains a constructor that initializes the deck of cards with appropriate values (e.g., “King of Hearts”), and a shuffle() method that randomly arranges the positions of the Cards in the array. The class also contains two abstract meb. Create two child classes that extend CardGame. You can choose any games you prefer. For example, you might create a Poker class or a Bridge class. Create a constructor for each child class that initializes the field that holds the number of cards dealt to the correct value. (For example, in standard poker, a player receives five cards, but in bridge, a player receives 13.) Create an appropriate displayDescription() and deal() method for each child class.
Write a class named Person with data attributes for a person’s name, address, and telephone number. Provide accessors/getters and mutators/setters for each attribute. Write a displayPerson() to print out the attributes of the Person. Next, write a class named Customer that is a subclass of the Person class. The Customer class should have a data attribute for a customer number, and a Boolean data attribute indicating whether the customer wishes to be on a mailing list. Provide accessors/getters and mutators/setters for each attribute. Write a display customer() to print out the attributes of the Customer. Demonstrate an instance of the Customer class in a simple program. All your programs will be modular. It will have the main() method that is executed first. Submit code that has no syntax error. And test your code, so as to not have logic errors. Each program must contain your name in the comments section and the date you created the code.
Write an abstract class, it can be anything well defined from the very basics.
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…
