Write a program to read a list of exam scores given as integer percentages in the range 0 to 100 and store them into an array. Make sure to validate the scores are within range. Display the total number of grades, and the number of each letter-grade using the following grading scale: 90 to 100 is an A 80 to 89 is a B 70 to 79 is a C 60 to 69 is a D 0 to 59 is an F Use a negative score as a sentinel value to indicate the end of the input. (The negative value is used only to end the loop, so do not use it in the calculations.)  For example, if the input is 98 87 86 85 85 78 73 72 72 72 70 66 63 50 −1 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

Question

Write a program to read a list of exam scores given as integer percentages in the range 0 to 100 and store them into an array. Make sure to validate the scores are within range.

Display the total number of grades, and the number of each letter-grade using the following grading scale:

  • 90 to 100 is an A
  • 80 to 89 is a B
  • 70 to 79 is a C
  • 60 to 69 is a D
  • 0 to 59 is an F

Use a negative score as a sentinel value to indicate the end of the input. (The negative value is used only to end the loop, so do not use it in the calculations.) 

For example, if the input is

98 87 86 85 85 78 73 72 72 72 70 66 63 50 −1

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
