You are developing a program to test the wireless network for a college campus - NSC Information Technology - Question 4 - 2023 - Paper 1

To add an access point, perform the following:

1. Extract the row and column values from the spin edits sedQ4_2_Row and sedQ4_2_Col.
2. Initialize a counter for access points in the row.
3. Loop through iCol from 1 to 6:
   • Check if arrNetwork[iRow, iCol] is 'A'. If true, increment the counter.
4. If the counter is 2 or less and if arrNetwork[iRow, iCol] is not 'A':
   • Add 'A' to arrNetwork[iRow, iCol] and display a success message.
5. However, if there's already an access point in that location, display a message indicating that.
6. If the row contains more than two access points, display a related message.

To determine coverage:

1. Loop through rows (iRow) from 1 to 5:
   • For each row, loop through columns (iCol) from 1 to 6.
   • If arrNetwork[iRow, iCol] equals 'A', apply the coverage as follows:
     • Loop for iRow from iRow - 1 to iRow + 1 and for iCol from iCol - 1 to iCol + 1 to check surrounding blocks.
     • Mark locations covered by this access point with an asterisk (*).
2. Finally, display the updated arrNetwork after all access points have been marked.
