Conference Registration System

Create an application that calculates the registration fees for a conference. The general conference

registration fee is $$895$ per person, and student registration is $$495$ per person. There is also an optional

opening night dinner with a keynote speech for $$30$ per person. In addition, the optional preconference

workshops listed in Table $13-10$ are available.

The application should allow the user to select the registration type, the optional opening night dinner and

keynote speech, and as many preconference workshops as desired. The total cost should be displayed.
