- C# Which statement is incorrect? Question 11 options: A Visual C# project can have multiple forms. Every form in a Visual C# project has a class. If a Visual C# project has a form named Form1, then the project cannot have a class named Form1. When you create event handlers for a specific form's controls, you write them as methods in that form's class.Account class • Design a class named Account that contains:• A private int data field named id for the account• A private double data field named balance for the account• A private Date data field named dateCreated that stores the datewhen the account was created• A no-arg constructor that creates a default account• A constructor that creates an account with the specified id andinitial balance• The getters (i.e., accessors) and setters (i.e., mutators) methods forid and balance• The getter method for dateCreated• A method named withdraw that withdraws a specified amount fromthe account• A method named deposit that deposits a specified amount to the account TestAccount class• Write a test program named TestAccount that performsthe following:• Create an Account object with an account ID of 1122 and abalance of 20,000 S.R.• Use the withdraw method to withdraw 2,500 S.R.• Use the deposit method to deposit 3,000 S.R.• Print the balance and the date when this account was createdCreate the class TopherAccount. Use the static read-write property AnnualInterestRate to store the annual interest rate for all account holders. Each object of the class contains a property TopherBalance, indicating the amount the client currently has on deposit. Provide method CalculateMonthlyInterest to calculate the monthly interest by multiplying the TopherBalance by AnnualInterestRate divided by 13—this interest should be added to TopherBalance. Write an app to test class TopherAccount. Create two TopherAccount objects, cliet1 and client2, with balances of $3400.00 and $4300.00, respectively. Set AnnualInterestRate to 4%, then calculate the monthly interest and display the new balances for both clients. Then set the AnnualInterestRate to 5%, calculate the next month’s interest and display the new balances for both clients.
