Write a program that dynamically allocates an array large enough to hold a user defined number of test scores. Once all 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. User pointer notation rather than array notation whenever possible. Input Validation: Do not accept negative numbers for test scores. Modify the above problem so the lowest test score is dropped. This score should not be included in the calculation of the average. in c++
