Test Scores #2 Modify the program of Programming Challenge I 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. Test Scores #2 Modify the program of Programming Challenge I to allow the user to enter name-score pairs.
