Implement a class Bank. This bank has two objects, checking and savings of type Account. Implement four member functions:

deposit(double amount, string account) withdraw(double amount, string account) transfer(double amount, string account) print_balance() The account string is "S" or " C". For the deposit or withdrawal, it indicates which account is affected. For a transfer it indicates the account from which the money is taken; the money is automatically transferred to the other account.

Test your program by using the main function below.

#include "Bank.h" using namespace std;

int main() { Bank my_bank; cout << "Inital bank balances: ";

my_bank.print_balances(); /* set up empty accounts */

cout << "Adding some money to accounts: "; my_bank.deposit(1000, "S"); /* deposit $1000 to savings */ my_bank.deposit(2000, "C"); /* deposit $2000 to checking */ my_bank.print_balances();

cout << "Taking out $1500 from checking,and moving $200 from"; cout << " savings to checking. "; my_bank.withdraw(1500, "C"); /* withdraw $1500 from checking */ my_bank.transfer(200, "S"); /* transfer $200 from savings */ my_bank.print_balances();

cout << "Trying to transfer $900 from Checking. "; my_bank.transfer(900, "C"); my_bank.print_balances();

cout << "trying to transfer $900 from Savings. "; my_bank.transfer(900, "S"); my_bank.print_balances();

return 0;

}

Output

Initial bank balances: Checking account balance: 0 Savings account balance: 0 Adding some money to accounts: Checking account balance: 2000 Savings account balance: 1000 Taking out $1500 from checking,and moving $200 from savings to checking. Checking account balance: 700 Savings account balance: 800 Trying to transfer $900 from Checking. Checking account balance: 680 Savings account balance: 800 trying to transfer $900 from Savings. Checking account balance: 680 Savings account balance: 780
