Write in C++

Write a program that dynamicall allocates an array large enough to hold a user-defined number of test scores. Once all of the scores are entered, the array should be passed to a function that sorts them in ascending order. Another function should be called that calculates the average score. the program should display the sorted list of scores and averages with appropriate headings. Use pointer notation rather than array notation whenever possible. DO NOT ACCEPT NEGATIVE NUMBERS FOR TEST SCORES Modify the program 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
