It has a GrossPay method that computes the gross pay of the employee. The method requires the number of hours worked (Double) as the parameter. Draw a button in the form. Set its Text property to Compute. When the user clicks the button, your program will create an employee object named TheEmployee. Set its SSN, Name, and HourlyRate properties to 123456789, ANIS ELIANI, and 70, respectively; then use its GrossPay
method to compute the gross pay for working 50 hours in a week (overtime pay is 1.5 times of the regular rate). Use a message box to display the following message:
(message box nk macam kt bawah)
ANIS ELIANI (employee number 123-45-6789) worked 50 hours, and
is paid $x,xxx (Replace x,xxx with proper amount.)
