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, 70-79= B ...so on). The end of the output is indicated by a negative score as a senital value. ( The negative value is used to end the loop, so do not use it in the calculations).
For example, if the input is
95
75
80
67
63
56
-1
the output would be
Total number of grades = 5
Number of A's = 1
Number of B's= 1
Number of C's = 1
Number of D's = 2
Number of F's = 1
