Question 3: PROBLEM-SOLVING PROGRAMMING

SCENARIO

Information centres, referred to as 'terminals', have been set up at three different points along the routes in the park. The management requires a software program to provide information to visitors to locate the different activities and facilities within Aqua Wonderland and to be aware of maintenance activities in the park.

Do the following:

Compile and execute the program in the Question3 folder. Currently, the program has no functionality.

Complete the code for each question as described in QUESTION 3.1 to QUESTION 3.4.

Supplied GUI

The supplied GUI represents a self-help interface to assist visitors in reaching various activities and facilities within the park.

Supply data:

You are provided with two parallel arrays and one two-dimensional array.

arrActivities is a one-dimensional array that contains the names of activities and facilities in the park. The data stored in this array are:

Water park, Aquarium, Sea, Restaurants, Shopping, Help desk, Penguin park, Shark tank, Dolphin shows

A corresponding parallel array called arrCodes contains letters from the alphabet, each representing the corresponding activity/facility described in the arrActivities array.

arrCodes contains the following elements:

W, A, S, R, X, D, H, P, T, L.

The first element (letter W) in the arrCodes array represents the first element ('Water park') in the arrActivities array, the second element (letter A) in the arrCodes array represents the second element ('Aquarium') in the arrActivities array, and so on.

arrArtCodes is a two-dimensional array that contains a combination of codes that represent activities and facilities that are accessible in a specific terminal when the visitor departs in a specific direction. The codes stored in this array are as follows:

Terminal 1: North SH, South SW, East DW, West PW

Terminal 2: North RS, South SR, East TW, West AT

Terminal 3: North H, South HY.

NOTE: The row and column headings are not provided as part of the two-dimensional array.

The activity code that applies when a visitor walks from Terminal 1 in a northerly direction is DWXAT.

Using the context of the arrCodes and arrActivities arrays, it can be established that:

Terminal 1, North, accesses the code DWXAT refers to two activities: 'Diving', 'Shopping'.

Button [3.1 – Activity/Facility codes for all terminals and directions]
The program must display the content of the two-dimensional array arrArtCodes neatly in rows and columns. Display the directions as column headings and the terminals as row labels.

Example of output:

Terminal 1   North   SHDURST   East   TSWP
Terminal 2   South   SROR  AT
Terminal 3   East   SH   HY

Button [3.2 – Activities/Facilities from a selected terminal and direction]
The buttons that contain images must be used to select a terminal and direction. Code is provided to assign the selected terminal and direction to variables. The program must then use these inputs to display the available activities and facilities corresponding to the selected terminal and direction. Display the selected terminal and the direction as well as a list of activities and facilities on the output area.

Example of output if Terminal 2 and South are selected:

Terminal 2, South activities are: Diving, Shopping.

Button [3.3 – Access routes to selected activity/facility]
Display the index of the activity/facility selected in the combo box.
Extract index of the activity/facility selected in the combo box. 
Set counter to 0.
Display heading.
Find the code of the selected activity.

Outer loop for rows.

Inner loop for columns.

Test if the code of the selected activity is a part of the code in the two-dimensional array.
Display the terminal number and the direction for each valid entry.
Increase counter by 1.
Display the label for the number of activities and the value of the counter.

Button [3.4 – Maintenance at a selected activity/facility]
The area where activities take place or facilities are provided may sometimes be closed due to maintenance. The user must select an activity/facility where maintenance must take place from the combo box. The program must remove the access code letter from the two-dimensional array and display a suitable message in a dialog box indicating that the information has been updated. The updated content of the two-dimensional array must be displayed in the output area.

Example of output if Diving was selected from the combo box:

The access routes to Diving are closed.
