Question 1. a, When the green flag is pressed any data stored is deleted. When the space key is pressed the user is asked to enter the pupils name into the first variable, followed by entering the pupils attendance, out of 50 days into the second variable, the user is then presented with the third variable, a percentage of the pupils attendance before the pupil is added to the appropriate list. b, A constant is a variable that does not change during the programme. An example used in this programme would be the variable ‘name’ which could be changed to PUPIL. c, d,1 d,2 An alternative form of selection structure to the attendance programme could be to change the percentage used for satisfactory attendance to 89% which will send 45 days attendance, equivalent to 90% to the satisfactory list and 44 days attendance, equivalent to 88% to the low attendance list. 1 This study source was downloaded by from CourseH on :32:18 GMT -05:00 .

If 1000 items already in ascending order were added, the comparisons would be 999 because the list is already sorted. There are 56 comparisons for flowerpot 2. My results for flowerpot 2 agree with the teacher's formula. n x (n-1) = 8 x 7 = 56. There are 240 comparisons for flowerpot 3. My results for flowerpot 3 agree with the teacher's formula. n x (n-1) = 16 x 15 = 240
