1.
Develop Visual Studio C# application for the following: An Abstract Class called Account has
two inherited classes: Checking Account and Savings Account. Create constructors and ToString
Methods for both accounts. Each type of account will also have a Balance and two methods:
Deposit and Withdraw. Account objects should be placed in a Generic List and they should
Polymorphically execute both Deposit and Withdraw methods. In the Main Method, start each
account with $1000 balance. Ask users to enter one deposit for each account, and one withdrawal
for each account and display the balance after each deposit and withdrawal. The application will
exit after the last withdrawal.
