Worked Solution & Example Answer:The trees at the nursery are categorised using the types Citrus, Deciduous, Nut, and Tropical - NSC Information Technology - Question 4 - 2019 - Paper 1
Step 1
Button [4.1 - Separate by type]
Answer
- Initialize a loop from 1 to the number of tree types (iTypes).
- Set the initial column to 0.
- Create an inner loop to loop through the elements in the arrList from 1 to 24.
- For each element, check if the last character of arrList[index] corresponds to the first character of arrTypes[row].
- Increment the column value in arrTrees[row, column] with the value of arrList[index].
- Enable buttons btnQ4_2 and btnQ4_3 after processing all elements.
Step 2
Button [4.2 - Display]
Answer
- Loop through each row from 1 to iTypes.
- Create a string variable sLine for displaying tree types. Append the corresponding trees from arrTrees[row, col].
- Utilize a nested loop to concatenate all relevant tree names into sLine.
- Display the final sLine in the output area.
Step 3
Button [4.3 - Sort alphabetically]
Answer
- Start with a loop from 1 to the number of tree types (iTypes).
- Within each iteration, loop through arrTrees to delete the last two characters of each tree name.
- Reassign each adjusted value to ensure proper sorting.
- Use a sorting algorithm to arrange the trees alphabetically by type.
- Finally, execute the display code in btnQ4_2 to show the updated list.
