Question

File for the Account class.
#include "Account.h"

bool Account::withdraw(double amount)
{
   if (balance < amount)
      return false; // Not enough in the account
   else
   {
      balance -= amount;
      transactions++;
      return true;
   }
}

//*********************************************************************************************************

class Account      // Account.h
{
private:
   double balance;         // Account balance
   double interestRate;    // Interest rate for the period
   double interest;        // Interest earned for the period
   int transactions;       // Number of transactions
public:
   Account(double iRate = 0.045, double bal = 0)
      { balance = bal;
        interestRate = iRate;
        interest = 0;
        transactions = 0; }

   void setInterestRate(double iRate)
      { interestRate = iRate; }

   void makeDeposit(double amount)
      { balance += amount;   transactions++; }

   bool withdraw(double amount); // Defined in Account.cpp

   void calcInterest( )
      { interest = balance * interestRate; balance += interest; }

   double getInterestRate( ) const
      { return interestRate; }

   double getBalance( ) const
      { return balance; }

   double getInterest( ) const
      { return interest; }

   int getTransactions( ) const
      { return transactions; }
};

Make the following changes to the Account class:

1. Add an array or vector to hold a sequence of transaction messages for the bank account. For each transaction, add an appropriate string message to this array or vector.

2. Add a string label (accountName) to the Account class to help identify the name of the account on the statement.

3. Write a member function called getStatement() that creates an account statement. The statement should include the account name along with the sequence of recent transaction messages. Ideally this method should return a string version of the statement to the calling program (i.e., that code prints the statement). If that’s not clear, it will also be acceptable to print the statement directly from this member function.

4. Account for the following types of transactions: New Account, initial deposit, deposit, withdrawal, interest payment.

5. Add a method called clearStatement() to reset or clear the statement.

Include a screenshot showing your Account class tested with the following program:

Create an Account called Mary Smith Savings, with an initial deposit of $10,000.

Transactions: withdraw $420, deposit $125, withdraw $215, interest payment at 1.1%

Print the statement Clear the Statement Transactions: withdraw $1894, deposit $825, interest payment at 1.1%

Print the statement
