Back to top

Create a new project that consists of the base class BankAccount.

The BankAccount class should contain, at minimum, the following members.

It should contain data members to store a bank customer's balance and account number. These should be of different and appropriate data types. It should have function members that do the following:

The checking account is allowed three free transactions. For each successful withdrawal transaction past the three free transactions, there will be a service fee of 50 cents per transaction. The service fee should be deducted from the account balance at the time the transaction is made. If there are insufficient funds in the account balance to cover the withdrawal plus the service fee, the withdrawal should be denied.
