Write a program that reads students names followed by their test scores (0-100). The program should output each students name followed by the test scores and the relevant grade. (90-100 = A, 80-89 = B, and so on) There could be any number of students and test scores entered so you will need to ask if the user is done entering students/scores before it moves on. It should also find and print the highest test score and the name of the students having the highest test score as well as calculate and display the average test score.
