Question

Write a program that uses pointer notation to dynamically allocate parallel array(s) large enough to hold a user-defined number of test scores and student names, using parallel arrays.

After student names and corresponding scores are entered, the array(s) should be passed to a function that sorts them in ascending order. Another function should be called that calculates the average score for the group (do not include the lowest score in the calculation of average grade). The program should display the sorted list of scores and student names, as well as the course’s average (use appropriate headings.)

Sample input data		Sample output
Jon Apple, 90 Jane Doe, 85 Bob Smith, 91 Tom Jones, 59 Susan Price, 70		Average: 84.5 Grade Student          91 Bob Smith 90       Jon Apple 85 Jane Doe 70 Susan Price 59 Tom Jones
