enum You will implement this enum in Visual Studio. There are seven members: Assignment 4 -
Implementing a Banking Application Due: See course shell for due date and time Check with
you professor to see if you are permitted to work as a group. The members are self-explanatory.
AccountType enum You will implement this enum in Visual Studio. There are three members:
The application is by far the most complex system that you have attempted so far. It consists of
eleven classes, two structs, one interface and two enums coupled in varying degrees of tightness.
The Bank class is the main driver of the application. It has collection of Accounts and Person
that is initialize appropriately in the static constructor. You will implement the entire system in
Visual Studio. A short description of each type with their members is given below. You are
advised to implement each type in the order that they are described. No method should have a
