NSC Information Technology Two-dimensional arrays: Three new malls have been built

Question

Three new malls have been built recently. Each mall has a ground floor that has shops to showcase the types of shops on the different levels at the mall. For example, if the ground floor has a clothing store, a restaurant and a furniture store, then the levels in the mall can only have the types of shops as showcased on the ground floor.

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 Question4.pas file.
- Compile and execute the program. The program has no functionality currently.

Example of the graphical user interface (GUI).

The following have been provided in the program:

- A one-dimensional array, arrShopTypes, consisting of the descriptions of 8 types of shops that can be at the mall.

arrShopTypes: array [1..8] of String = ('Electronics', 'Jewellery', 'Furniture', 'Clothing', 'Restaurant', 'Toys', 'Laundry', 'Gifts');

- Three text files, one for each of the three different malls (Kensley, Barbedos, Maistry). Each line of the text file represents a level in the mall. For example, the text file named 'Kensley' contains six lines of text which represent the type of shops in the mall per level.

Each character in a line of text represents a type of shop (the first letter of the given list of shop types in array arrShopTypes) that can be found on that specific level in the mall. For example, the letter E refers to Electronics, J refers to Jewellery and so on. The characters used are E, J, F, C, R, T, L and G.

The second line of the text file for the Kensley Mall contains the following line of text, 'JCFEFCFELF', which indicates that there are shops on level 2 of the mall - one jewellery shop (J), two clothing shops (C), one furniture shop (F), three electronics shops (E), one restaurant (R) and one laundry (L).

Write code to perform the tasks described in QUESTION 4.1 to QUESTION 4.2.

4.1 Button [4.1 - Populate and display array]

The user must select a mall from the radio group rgpQ4.

- Use the text of the radio button selected to compile the file name which indicates which text file to read.
- Read the contents of the text file into an array. The maximum number of levels in a mall is 6.
- Display the lines of text representing the type of shops in the mall per level and the number of shops per level, as shown in the screenshot below. The display of the shops must be right-justified. You can assume that the maximum length of a line of text with the types of shops, including the spaces, is 25.

Example of output if the 'Kensley' mall was selected:

Level:   Shops:                        Number of shops per level:
----------------------------------------------------------
1.       LEJCF                       5
2.       JCFEFCFELF                 16
3.       JECCFRRJEFFRRR            15
4.       JECRFCFECFFF               18
5.       JECLLJL                     3
6.       FFLFELJJCFFC               12

Example of output if the Barbedos Mall was entered and C was selected as the shop type:

Level:   Shops:                        Number of shops per level:
----------------------------------------------------------
1.       JEJCF                    5
2.       JCFECF                 16
3.       JEJEFCFFFF           15
4.       JECCFRRFF            26
5.       3C                     5
6.       JFJECFFL               12

Type of shop: Furniture
Number per level
1.       2
2.       1
3.       3
