NSC Information Technology Code optimization: Efforts are made to identify and

Question

Efforts are made to identify and improve code segments in the current software system utilised by the administration department.

Study the extract of Delphi code below and answer the questions that follow:

```pascal
   iCounter := 0;
   for iRow := 1 to 3 do
   begin
     sLine := '';
     for iCol := 1 to 5 do
     begin
       sLine := sLine + '*';
       inc(iCounter);
     end;
   end;
   redOutput.Lines.Add(sLine);
```

5.1.1 Write down the line number of any line of code from the provided code segment above that implements the following:

(a) Initialisation  
(b) Looping

5.1.2 What will be the value of iCounter after the above code has been executed?

NOTE: Assume that all the variables are declared correctly and there are no errors in the code.

5.1.3 Provide the output of the program after the code above has been executed.

5.1.4 Rewrite the second loop (for iCol := 1 to 5 do) as a conditional loop.
