Key points when answering questions are the marks given for it and how the question is defined. In this example we need to write a pre-condition loop to output all the even numbers in the range (99,201), and so it gives 4 marks for it. First of all we need to write a while loop because of the pre-condition loop requirement and set a counter to keep count of the numbers we need (in this case we take the first even number after 99 which is the 100). Then we increment the counter by 2 (since we need just even numbers) and set the ending condition to the range of numbers set (which is 201).Counter <- 100 WHILE Counter < 201 Output Counter Counter <- Counter + 2 ENDWHILE
