Design a class named Person with properties for holding a person’s name, address, and telephone number. Next, design a class named Customer, which is derived from the Person class. The Customer class should have a property for a customer number and a Boolean property indicating whether the customer wishes to be on a mailing list. Demonstrate an object of the Customer class in a simple application.

use C++ programming language. Design and implement a class dayType that implements the day of the week in a program. The class dayType should store the day, such as Sun for Sunday. The program should be able to perform the following operations on an object of type dayType: Set the day. Print the day. Return the day. Return the next day. Return the previous day. Calculate and return the day by adding certain days to the current day. For example, if the current day is Monday and we add 4 days, the day to be returned is Friday. Similarly, if today is Tuesday and we add 13 days, the day to be returned is Monday. Add the appropriate constructors.

What is the design pattern depicted in the diagram below? The intent of this design pattern is to define an interface for creating an object, but let subclasses decide which class to instantiate. It lets a class defer instantiation to subclasses.

Help, I making a elevator simulator. I have to use polymorphism and object oriented programming to write this code. Can someone please help me improve this code I have. The remaining code is in the pictures. Any help is appreciated. Thank You! The simulation should have 4 types of Passengers: Standard: This is the most common type of passenger and has a request percentage of 70%. Standard passengers have no special requirements. VIP: This type of passenger has a request percentage of 10%. VIP passengers are given priority and are more likely to be picked up by express elevators. Freight: This type of passenger has a request percentage of 15%. Freight passengers have large items that need to be transported and are more likely to be picked up by freight elevators. Glass: This type of passenger has a request percentage of 5%. Glass passengers have fragile items that need to be transported and are more likely to be picked up by glass elevators. The simulation should also have 4 types…

Define a Card class which contains three PRIVATE (why?) variables for card suit, face value and the third (could be Boolean) to indicate if the card is drawn or not (these are states of a card object) plus operations that can be performed on a card (these are behaviors), The operations include: · Define 3 pairs of accessor and mutator methods for accessing these 3 private variables of a card respectively · Define a constructor that takes three parameters (suit and face value) to instantiate a card with the third parameter indicating that the card has not been drawn at the time of creation of the card. · Define (Override) the method toString to display the card (show both suit and face value) · Define one drawcard method that randomly draws a card by first checking if the card has been drawn. If the card has been drawn, the method has to draw another card that has not been drawn and the method returns a card object. This method looks like: public Card…
