Write a C++ program to play the dice game "Craps". Craps is one of the most popular games of chance and is played in casinos and back alleys throughout the world. The rules of the game are straightforward:
A player rolls two dice. Each die has six faces. These faces contain 1, 2, 3, 4, 5, and 6 spots. After the dice have come to rest, the sum of the spots on the two upward faces is calculated. If the sum is 7 or 11 on the first throw, the player wins. If the sum is 2, 3, or 12 on the first throw (called "craps"), the player loses (i.e. the "house" wins). If the sum is 4, 5, 6, 8, 9, or 10 on the first throw, then the sum becomes the player's "point." To win, you must continue rolling the dice until you "make your point." The player loses by rolling a 7 before making the point.
At a minimum, your solution must contain the functions below.
void displayGameRules()
int rollOneDice()
int rollTwoDice()

At your last 6 fill-ups the mileage was
65311 65624 65908 66219 66499 66821 67145 67447. Enter these

Task
Answer the following essay question:
"All technological change is a Faustian bargain. For every advantage a new technology offers, there is always a corresponding disadvantage"
Is this statement valid? Discuss Postman's observation
in the context of educational technology in contemporary Australian
higher education.
Postman, N. (1995). The end of education: Redefining the value
of school. New York: Alfred A. Knopf.
Overview and Advice
'Higher education' in this question refers to post-compulsory education. While some research may be relevant to K-12, the focus of your discussion should be further education including University, TAFE and trade training, as this raises different issues around motivation, goals and outcomes. Remember that we are interested in evidence-based practice, so statements about participation, attitudes, behaviour and outcomes should be supported with peer-reviewed research and demographic data.
Careful question analysis is important when approaching this essay. What does discuss mean? This topic is potentially broad, so you will need to plan carefully to ensure that your argument is clearly defined and follows a logical progression. Question your own assumptions, and those of the authors you are reading; look for opportunities to demonstrate critical thinking. Use good essay and paragraph structure, and demonstrate your understanding of referencing by supporting your argument with a wide selection of carefully chosen sources.
Important: We are interested in investigating the pros and cons of technology in education; this essay is not about Postman’s broader views, or his work; only the statement presented in the question (which should be mentioned in your introduction).

(Main Focus of Cheg-Study!)
// this is the question below
You will create specific customer classes with specialized behaviors for a regular subscription and platinum
subscription. This will focus on the concepts of inheritance and polymorphism.
Main objective. This will consist of four classes: Customer, RegularCustomer, PlatinumCustomer, and
Tester (or any name you’d prefer for the main method file). The Customer class will have a
name and type. The RegularCustomer and PlatinumCustomer classes will inherit both of these
fields from the Customer class. The PlatinumCustomer class will also have a discount field. The
methods for each of these classes will be the following:
Customer
* Customer (constructor)
* setName
* setType
* getName
* getType
* toString
RegularCustomer:
* RegularCustomer (constructor)
* toString
PlatinumCustomer
* PlatinumCustomer (constructor)
* setDiscount
* getDiscount
* toString
For the RegularCustomer and PlatinumCustomer constructors, the type of subscription should
be set to “regular” or “platinum". Each of these two constructors should also take
advantage of inheritance when setting the fields. Given a name of “David” and a type of
“regular”, the toString method for Customer and RegularCustomer should print the following:
David has a regular subscription.
The toString method for PlatinumCustomer should also include the discount. Assume a discount
of 7% for the following:
David has a platinum subscription. The current discount on purchases for this subscription is
7.0%.
In the Tester class, make a main method where you create a Customer reference variable. Ask
the user to input a type. If the user enters “regular” for the type, ask for the name and construct
a RegularCustomer object. If the user enters “platinum” for the type, ask for the name and a
discount and then construct a PlatinumCustomer object. Finally, print this created object
to the console.
Take note of one issue with this design. RegularCustomer and
PlatinumCustomer both inherit setType from Customer, but the user should never be able to
change the type for either of these subclasses. Implement an overriding setType for each of
these two subclasses that prevents the type from being changed.
The workflow of the main method should be similar to the following:
For a Regular Subscription;
run:
Please enter a type: regular
Please enter a name: David
David has a regular subscription.
Build successful (total time: 6 seconds)
For a Platinum Subscription;
Please enter a type: platinum
Please enter a name: David
Please enter a discount: 7
David has a platinum subscription.
The current discount on purchases for this subscription is 7.0%
Build successful (total time: 6 seconds)

Exercise 4: Perform the following on the Account class and test it in the AccountArrayTest: In the AccountArrayTest class, add a static method called getAverageBalance (Account accounts[]) that returns the average balance of all accounts. Use the enhanced for loop. In the main method get and print the average accounts balance. Add an instance method called deposit() that takes a double amount as parameter and if it is positive it adds it to the current balance. If the amount is less than or equal to zero it does nothing. Add a static method called addInterest(Account accounts[]) that calculates the interest for each account in the accounts array (based on the interestRate value), and then deposits it into the relevant account in that array. (Hint: interest = interestRate * balance/100). Use the above methods to apply the addInterest() for all the accounts in your AccountArrayTest. Print the accountNo and balance after the update.
