a. Watson Elementary School contains 30 classrooms numbered 1 through 30. Each classroom can contain any number of students up to 35. Each student takes an achievement test at the end of the school year and receives a score from 0 through 100. Write a program that accepts data for each student in the school—student ID, classroom number, and score on the achievement test. Design a program that lists the total points scored for each of the 30 classrooms.

b. Modify the Watson Elementary School program so that the average of the test scores is output for each classroom, rather than total scores for each classroom.
