PROBLEM and INSTRUCTIONS

Develop a C++ program to implement online banking service for the customers.

Each customer will create one checking account and one savings account.

Both accounts have account number, balance, owners first name, last name, address and email.

Customer could select to display account information, deposit money, withdraw money and transfer money for both accounts.

The checking account will charge $5.00 transaction fee for each deposit, withdraw and transfer money transaction.

The savings account will generate interest with 2% interest rate. Suppose the interest is 2% of the current balance.

All transactions should be validated by checking:

The amount of deposit, withdraw and transfer should be positive value or 0.

There should have sufficient balance in the account to perform withdraw or transfer transactions.

The appropriate message should be displayed after each transaction.

Attempt to withdraw money from the account which has insufficient balance.

Specific message should be displayed to user.

Declare and implement class Customer with at least the following members: Data members:

firstName

lastName

address

email

Member functions:

Customer() - default constructor without parameter.

Customer() - overloaded constructor with parameters of initial value of all data members.

void displayCustomer() - display all customers information.

Declare and implement an abstract base class Account with at least the following members: Data members:

accountNumber

balance

user - should implement composition to create an object of Customer class.

Member functions:

Account() - default constructor without parameter.

Account() - overloaded constructor with parameters of initial value of all data members.

double getBalance() - return current balance of an account.

void setBalance() update balance with argument value.

bool deposit(double amount) -

parameter is the deposit money entered by user

only perform deposit transaction for valid amount and return true, otherwise, return false without changing the balance.

bool withdraw(double amount) -

parameter is the withdraw money entered by user

only perform withdraw and return true if amount is valid and there is sufficient balance in the account. Otherwise, return false without changing the balance.

virtual void displayAccount()

this function should be declared as a virtual function.

it will be overridden by the function in the derived classes in order to implement polymorphism in the tester program.

it should display account number, balance and account users information by calling Customers displayCustomer() function

Declare and implement a derived class CheckingAccount which inherits from base class Account and includes at least the following members: Data members:

transactionFee

Member functions:

CheckingAccount() constructor with parameters of initial value of all data members including the data members inherited from the base class Account.

double getTransactionFee() return the transactionFee

bool deposit(double amount)

override the deposit function in base class Account.

call Accounts deposit function to implement deposit.

charge the transaction fee only if the deposit is implemented successfully by the base class.

bool withdraw(double amount)

override the withdraw function in base class Account

call Accounts withdraw function to implement withdraw.

charge the transaction fee only if the withdraw is implemented successfully by the base class.

void displayAccount()

keep the same name as that in the base class Account in order to implement polymorphism in the tester program.

Override the displayAccount function in the base class by displaying the title of Checking Account and transaction fee.

Declare and implement a derived class SavingsAccount which inherits from base class Account and includes at least the following members: Data members:

interestRate

Member functions:

SavingsAccount(.) - constructor with parameters of initial value of all data members including the data members inherited from the base class Account.

double getInterestRate() return the interestRate

double calcInterest()

calculate the interest, suppose interest = balance * interestRate.

update balance by adding the interest.

return interest.

void displayAccount()-

keep the same name as that in the base class Account in order to implement polymorphism in the tester program.

Override the displayAccount function in the base class by displaying the title of Savings Account, interestRate and interest.

Implement the following tasks in the tester program:

Ask user to enter users information.

Create an object of CheckingAccount for the customer using the input data.

Default account number is 1111.

Transaction fee is $5.00 for each transaction.

Create an object of SavingsAccount for the customer using the input data.

Default account number is 2222.

Interest rate is 2%.

Define a loop to display the service menu and ask user to select the service continually.

Define switch or nested selection structure to process users selected transaction.

Implement object-oriented programming to process users selected transaction.

Implement dynamic binding polymorphism for Display accounts option

Create a dynamic array of Account with 2 elements.

Store the address of checking account object and savings account object in the array.

Use a for loop to call displayAccount function, the derived class version will be implemented to display checking accounts information and savings accounts information appropriately.

Use could exit the program appropriately.

Here is the template of tester program

#include

#include

#include "Account.h"

#include "CheckingAccount.h"

#include "SavingsAccount.h"

using namespace std;

int main()

{

int selection = 0;

string firstName = "";

string lastName = "";

string address = "";

string email = "";

double amount = 0.0;

// input users information

// write your code here

// create CheckingAccount object

// write your code here

// create SavingsAccount object

// write your code here

cout << "Your checking account and savings account are created successfully. " << endl << endl;

// display the menu and ask for the first selection from user

// write your code here

while (selection != 8)

{

switch(selection)

{

case 1:

// implement polymorphism

// to display accounts information

case 2:

// deposit to checking account

// write your code here

case 3:

// deposit to savings account

// write your code here

case 4:

// withdraw from checking account

// write your code here

case 5:

// withdraw from savings account

// write your code here

case 6:

// transfer money from checking account to savings account

// write your code here

case 7:

// transfer money from savings account to checking account

// write your code here

default:

cout << "Invalid selection." << endl;

}

// display the menu and ask for next selection from user

// write your code here

}

cout << "Thanks for using Bank of Wake!" << endl;

return 0;

}
