Grade Calculator: GradeCalculator.cpp Write a program that reads student scores, gets the best score (BestScore), and then assigns letter grades based on the following scheme: A: [BestScore, BestScore 10]

B: (BestScore 10, BestScore 20]

C: (BestScore 20, BestScore 30]

D: (BestScore 30, BestScore 40]

F: Lower than BestScore 40. The program should prompt the user to enter the total number of students, then prompt the user to enter all of the scores, and conclude by displaying the letter grades. Here is a sample run:

Enter the number of students: 4

Enter 4 scores: 40 55 70 58

Student 0 Score: 40, Letter: C

Student 1 Score: 55, Letter: B

Student 2 Score: 70, Letter: A
