Use your exercise $6$ implementation.$$

Add "PrintBalance" method to your Account class

Create two new classes:

CheckingAccount must inherit from Account classSavingsAccount must inherit from Account class

You must re$-$factor $($make necessary changes$)$ your code to use the new classes.

Exersize $6$: Create a set of classes that describe a bank and the different types of bank accounts:$$

Checking Account$$Savings Account$$

Add the following methods to each bank account:$$

CloseAccount: Used when a bank account must be closed.$$AddFunds: Used when we need to add funds to the account.$$CheckBalance: Used when we need to check current balance on account.$$GetTransactionCount: You must keep track of the # of transactions on the account.$$

The bank must have a property that keeps track of all its members$$

The bank must have a balance, which is affected based on user transactions$$

The bank must have the following methods:$$

ListAllMemebers$$GetAccountTypeCount$$GetTransactionCount
