a) Write C++ statements for the algorithms in Figure 2Initialize total to zero Initialize counter to zero Input the first mark while the user has not as yet entered the sentinel add this mark into the running total add one to the mark counter input the next mark (possibly the sentinel) endwhile if the counter is not equal to zero set the average to the total divided by the counter print the average else print 'no marks were entered' endir Figure 2.

b) Write C++ statements for the algorithm in Figure 3. (10 marks) initialize passes to zero initialize failures to zero initialize student to one while student counter is less than or equal to ten input the next exam result if the student passed, ie mark is 60 or more add one to passes else add one to failures endir add one to student counter endwhile print the number of passes print the number of failures if eight or more students passed print "raise tuition" endir Figure 3.
