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.

Supplied 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, Diving, 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.

The arrCodes array contains the following elements:

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

The first element (W) in the arrCodes array represents the first element ('Water park') in the arrActivities array, the second element (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 from a specific terminal when the visitor departs in a specific direction. The codes stored in this array are as follows:

Terminal 1: North - WRSAT
Terminal 1: South - WLSR
Terminal 2: East - ATX
Terminal 2: West - SHD
Terminal 3: North - SLMP
Terminal 3: South - TWSD

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 DDXAT.

Using the content of the arrCodes and arrActivities arrays, it can be established that the information displayed in the code DDXAT refers to two activities: Shopping and Diving.

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:

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 variables to display the selected activities and facilities from that terminal. Display the selected terminal and the direction as well as the activities and facilities on the output area.

Example of output if Terminal 2 and South are selected:

Terminal 2, South
Activities:
Water park
Aquarium
Sea

Button [3.3 - Access routes to selected activity/facility]

Display the index of the activity/facility selected in the combo box.
Set counter to 0.
Display heading.
Find the code of selected activity.

The outer loop for rows. The inner loop for columns. Test if the code of the selected activity is part of the code in the two-dimensional array. Display the terminal number and the direction, and increase counter by 1.

Display the label for the number of activities and the value of the counter.

Button [3.4 - Maintenance at 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 provided. The program must remove the access routes 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.

Example of output after removing the letter D from the two-dimensional array arrArtCodes due to maintenance that must be done on the diving facility:
