Develop three classes called Bank, Account, and Customer to store account information and its customer information for a bank.

Bank Class

Your Bank class should have a maximum of five accounts. For the openAccount() method, your class should add a new account with the account number (accNum) and the corresponding information. Additionally, your method should put the customer information with the SSN number in the Account object. If the account number is already taken by another object or the bank already has too many accounts (= five), your method should return false. Furthermore, if a customer with the SSN already has an account in the bank, your method should return false as well.

For the closeAccount() method, your class should delete the account with the account number (accNum) from the bank. If the account number doesnt exist in the bank, your method should return false.

For the accountInfo() method, your class should display the account information with the corresponding customer information. If the account number doesnt exist in the bank, your method should return false.

For the updateBalance() method, your class should change the balance with the new amount for the account number. If the account number doesnt exist in the bank or the balance is a negative number, your method should return false.

For the updateAddress() method, your class should update the address of the customer with the account number. If the account number doesnt exist in the bank, your method should return false.

Account Class

Note:

For accType, 1 is checking and 2 is savings.

accountholder holds the Customer object for the account.

One Account object can have only one account holder (= Customer).
