Question
You are a programmer for the Home Software Company. You have
been assigned to develop a class that models the basic workings of a
bank account. The class should have the following properties:
• Balance: Holds the current account balance.
• IntRate: Holds the interest rate for the period.
• Interest: Holds the interest earned for the current period.
• Transactions: Holds the number of transactions for the
current period. The class should also have the following
methods:
MakeDeposit Takes an argument, which is the amount of the
deposit. This argu- ment is added to the Balance
property.
Withdraw Takes an argument that is the amount of the
withdrawal. This value is subtracted from the
Balance property, unless the with- drawal amount is
greater than the balance. If this happens, an error
message is displayed.
CalcInterest This method calculates the amount of interest for
the current period, stores this value in the Interest
property, and adds it to the Balance property.
Demonstrate the class in an application that performs the following tasks:
• Allows deposits to be made to the account.
• Allows withdrawals to be taken from the account.
• Calculates interest for the period.
• Reports the current account balance at any time.
• Reports the current number of transactions at any time
