Create the FormTestBankAccount form design in Visual C# that closely resembles the GUI which
appears on the last page
4. Change the label “Programmer: name” by replacing name with your real name.
5. Write the Visual C# code
a. Update the code for the BankAccount class to make it abstract.
b. Create a SavingAccount subclass of BankAccount.
c. Create a CheckingAccount subclass of BankAccount.
Update the BankAccount class to be an abstract class and create two classes
SavingAccount and CheckingAccount which are direct subclasses of BankAccount.
Update the BankAccount class to:
1) Be an "abstract" class
2) Make fields "protected" so subclasses can access them.
3) Convert the Deposit and Withdraw functions to be "abstract" (remove any code from them, the
code will be written in the subclasses)
