Dear,

Here is the solution for BankAccount...

//Header section

#include

using namespace std;

//Base class BankAccount

class BankAccount

{

//Data members

public:

       int accountNumber;

       double balance;

public:

          //Constructor

       BankAccount(int ano,double bal)

       {

              accountNumber=ano;

              balance=bal;

       }

       BankAccount() { }

public:

     //Accessor methods for getting balance

     double getBalance()

       {

             return(balance);

       }

     //Accessor methods for getting account number

       int getAccountNumber()

       {

              return(accountNumber);

       }

        //Mutuator method to set balance

        void setBalance(double amount)

       {

              balance=amount;

       }

        //Setting account number

        void setAccountNumber(int ano)

       {

              accountNumber=ano;

       }

        //show account information

       void virtual showAccountInfo()

       {

              cout<<"Account Number :"<

              cout<<"Account Balance:"<

       }

        //function to perform deposit

       double virtual depositAmount(double damount)

       {

             balance=balance+damount;

              return(balance);

       }

        //withdrawl amount

       double virtual withDrawAmount(double wamount)

       {

             balance=balance-wamount;

              return(balance);

       }

};//End of class
