Tutorial 1

Create C# projects of Windows Forms App and Console App using Microsoft Visual Studio 2022 for the following scenario:

A payment kiosk is used by staff and customers to pay for parking tickets.

Parking rules are as follows:

Staff:

1.  The parking charges for the first ten hours are $2.00.

2.  Further parking beyond 10 hours will incur a charge of $2.00 per hour.

3.  Parking time cannot exceed 24 hours. If a car is parked for more than 24 hours, it will be towed away.

Customer

1.  The parking charges are based per hour. Parking per hour = $ 2.00

2.  Parking time cannot exceed 24 hours. If a car is parked for more than 24 hours, it will be towed away.

The program should display the parking charges for each staff or customer. Charges are calculated based on the number of hours a car has been parked.

You have to make a two-tier design:

Class Design

Identify what classes you are going to use. What will be the fields, properties and methods?

Hints: 1.   Useful Math functions: Math.Ceiling, dai 写158.326 Software Construction Tutorial 1 Math.Abs(x), Math.Floor(x), Math.Max(x,y), Math.Min(x,y) If a person has parked for 3.5 hours, the kiosk will charge him for 4 hours. So, use Math.Ceiling function Math.Ceiling(3.5) = 4 2.   To display output in currency format – use ToString(“C”) (refer to http://msdn.microsoft.com/en-us/library/dwhawy9k(v=vs.110).aspx

The parking amount varies for customer and staff

If parking exceeds 24 hours, an exception is thrown from a class member and caught by the form
