Question 4 - Problem-solving programming

The Parking Group has requested your assistance for the implementation of the calculation of cost when vehicles exit a parking area.

Do the following:

- Open the incomplete program in the Question 4 folder.
- Enter your examination number as a comment in the first line of the QuestionU.pas file.
- Compile and execute the program. The program has no functionality currently.

Example of graphical user interface (GUI):

4.1 Button [4.1 - Display]
Write code to display the number, registration number and time of entry for the vehicles stored in arrays arrRegNumbers and arrEntryTimes in the rich edit component nedQ4.

Example of output:

RegNumber   | Time In
-------------------------
CA 123 456  | 10:00
BEC 123 BC  | 10:15
XRG 123 L   | 10:30

4.2 Button [4.2 - Exit parking area]
The amount of time a vehicle spent in the parking area is used to determine the tariff per hour and calculate the cost of parking. The tariff for parking per hour is determined as follows:

When a vehicle exits the parking area, the following must be done:

- Select the vehicle’s registration number from the combo box cmbQ4.
- Enter the exit time in the edit box edtQ4 in the format hh:mm.
- A message 'Invalid exit time' must be displayed in the rich edit component nedQ4 when an attempt is made to enter an exit time that is earlier than the entry time for the vehicle selected. If the time is valid, processing can proceed.

The cost of parking must be calculated using the following formula:

Cost of parking = Tariff * Time spent in parking area

NOTE: Minutes must be rounded up to the next whole hour when calculating the cost.

The registration number, entry time, exit time, time spent in the parking area, tariff and cost of parking must be shown in the rich edit component in the form shown in the example below:

Example of input and output:

Registration number: CA 123 456
Entry time: 10:00
Exit time: 13:05
Time spent: 3 hours 5 min
Tariff per hour: R40.00
Cost of parking: R120.00

HINT: Click on the Display button to see if the information has been removed from the arrays correctly.
