The following C++ program example 4.26 computes the sum of 10 positive integers
              using for loop. The output is shown in Figure 4.51.

                    Activity 4.6:
                                                            displays total marks and average
                Difference between the ‘while loop,         marks for each student, using:
                do….while loop and for…loop’                (i)   while…..loop

               (a) Write three C++ programs to              (ii)  do-while…loop
                   display students’ results. Each          (iii)  for.... loop
                   program prompts a user to enter       (b) Compare the results generated from

                   the number of students in the class      each loop
                   and the marks of five (5) subjects    (c) Comment on the results obtained
                   for each student. Then, the program      from each loop.
