Answer
The initialisation can be found in line 1: iCounter := 0;. This line sets the counter variable to zero, which is crucial for beginning the counting process.

Answer
The looping statement is found in line 5: for iCol := 1 to 5 do. This line establishes a loop that will iterate five times, which is essential for generating the output.
Step 3
5.1.2 What will be the value of iCounter after the above code has been executed?

Answer
After executing the code, iCounter will have the value of 15. This is because the outer loop runs three times (for iRow) and the inner loop runs five times (for iCol), leading to a total of 3 * 5 = 15 increments.
Step 4
5.1.3 Provide the output of the program after the code above has been executed.

Answer
The output of the program after execution will be a single line containing five asterisks: *****. This is because the inner loop appends an asterisk to the string sLine five times for each iteration of iRow.
Step 5
5.1.4 Rewrite the second loop (for iCol := 1 to 5 do) as a conditional loop.

Answer
To rewrite the loop as a conditional loop, you can use a while loop as follows:
iCol := 1;
while iCol <= 5 do
begin
sLine := sLine + '*';
inc(iCounter);
inc(iCol);
end;
