Question

1.   Design a class called BankAccount. The member fields of the class are: Account Name, Account Number and Account Balance. There are also other variables called MIN_BALANCE=9.99, REWARDS_AMOUNT=1000.00, REWARDS_RATE=0.04. They look like constants, but for now, they are variables of type double
Here is the UML for the class:
                                                        BankAccount
-string accountName // First and Last name of Account holder
-int accountNumber // integer
-double accountBalance // current balance amount
+ BankAccount()                     //default constructor that sets name to “”, account number to 0 and balance to 0
+BankAccount(string accountName, int accountNumber, double accountBalance)   // regular constructor
+getAccountBalance(): double // returns the balance
+getAccountName: string // returns name
+getAccountNumber: int
+setAccountBalance(double amount) : void
+withdraw(double amount) : bool //deducts from balance and returns true if resulting balance is less than minimum balance
+deposit(double amount): void //adds amount to balance. If amount is greater than rewards amount, calls
// addReward method
-addReward(double amount) void // adds rewards rate * amount to balance
+toString(): String   // return the account information as a string with three lines. “Account Name: “ name
                                                                                                                      “Account Number:” number
                                                                                                                      “Account Balance:” balance

2.   Create a file called BankAccount.cpp which implements the BankAccount class as given in the UML diagram above. The class will have member variables( attributes/data) and instance methods(behaviours/functions that initialize, access and process data)

3.   Create a driver class to do the following:
a.   Declare and instantiate a bank account called accountZero using the default constructor
b.   Declare and instantiate a bank account called accountOne with name= “Matilda Patel” number =1232, balance=-4.00
c.   Declare and instantiate a bank account called accountTwo with name = “Fernando Diaz”, number=1234, balance=250
d.   Declare and instantiate a bank account called accountThree with name=”Howard Chen”, number=1236, balance = 194.56
e.   Display the bank accounts in the three line format as above
f.   Deposit 999 dollars in Fernando’s account and 1000.25 in Howards account
g.   Display their account information
h.   Withdraw 10000 from Matildas account and 90 dollars from Feranandos account
i.   Display the results. If withdrawal is not possible your program should say “Insufficient funds” otherwise it should say “Remaining Balance :” balance amount
j.   Print the total amount of all the bank accounts created.
