2. The problem Write a program to read a list of exam scores (integer percentages in the range 0 to 100) and to output the total number of grades and the number of grades in each letter-grade category (90 to 100 = A, 80 to 89 = B, 70 to 79 = C, 60 to 69 = D, and 0 to 59 = F). The end of the input is indicated by a negative score as a sentinel value. (The negative value isused only to end the loop, so do not use it in the calculations). (Example on next slide)

3. Problem (continued) For example, if the input is 98 87 86 85 78 73 72 70 66 63 50 the output would be: Total number of grades = 14 Number of A’s = 1 Number of B’s = 4 Number of C’s = 6 Number of D’s = 2 Number of F’s = 1
