Test Scores #2

Modify the program of Programming Challenge 1 to allow the user to enter name–score

pairs. For each student taking a test, the user types a string representing the name of the

student, followed by an integer representing the student’s score. Modify both the sorting

and average-calculating functions so they take arrays of structures, with each structure

containing the name and score of a single student. In traversing the arrays, use pointers

rather than array indices.
