Write a program that reads a list of exam grades entered as int's in the range of 0 to 100. The program must report the total number of grades and the number of grades in each letter-grade category, where the letter-grade categories are as follows: 93 <= grade <= 100 90 <= grade < 93 87 <= grade < 90 83 <= grade 87 80 <= grade < 83 77 <= grade < 80 73 <= grade < 77 70 <= grade < 73 60 <= grade < 70 0 <= grade < 60 The program must use a negative number as a sentinel value to indicate the end of the input. By definition the negative sentinel value is used only to end the loop. Do not use it in the calculations. The program will prompt the user to enter each grade individually by printing: Enter a grade: A A- B+ B B- C+ с C- D F If the inputs are: 98 95 87 86 83 92 85 78 74 72 81 71 69 63 50 43 -1 The output would be: Total number of grades = 16 Number of A's = 2 Number of A-'s = 1 Number of B+'s = 1 Number of B's 3 Number of B-'s = 1 Number of C+'s = 1 Number of C's = 1 Number of C-'s = 2 Number of D's = 2 Number of F's = 2 Please note that your class should be named Grades.
