The programme in (1c) computes and outputs the total number of loaves of bread sold, the total money made, and the average number of loaves sold by each student. However, the programme assumes that the programmer knows the exact number of volunteers. Now suppose that you do not know the exact number of volunteers. Modify your programme in 1 i), assuming that the data is in the following form: student’s index number followed by a space and the number of loaves sold by the student. Since you do not know the exact number of volunteers, assume that -1 will mark the end of the data.
