Create a component named EmployeeLib. Include in it the abstract Employee class from Figure 12-36. Also, create a SalesEmployee class that inherits from Employee. The class will contain properties that hold the employee’s base pay, sales quota, sales amount, and commission rate. Use the following formula to calculate the employee’s gross pay:
base pay + ((sales amount – sales quota) * commission rate)
If the sales amount is less than the sales quota, however, the gross pay should just equal the base pay.
Add a Windows Forms application to the Visual Studio solution. Its startup form must let the user input the employee name, base pay, sales quota, sales amount, and commis- sion rate. Then when a button is clicked, the application must display the person’s name, gross pay, tax, and net pay.
