Grader program
Project objective: write a program that takes a list of final scores for a class and determines: 1) the mean (Greek letter mu), 2) the standard deviation (Greek letter sigma), and 3) the number of grades in each category (A, A, B+, B, C+, C, C, D+, D, and F). \
Prompt the user for the name of a file containing the final scores, up to 100 scores, such as (without the commas):
100, 94, 59, 83, 57, 11, 92, 76, 37, 89, 74, 59, 65, 79, 49, 89, 89, 75, 64, 82, 15, 74, 82, 68, 92, 61, 33, 95, 91, 82, 89, 64, 43, 93, 86, 65, 72, 40, 42, 90, 81, 62, 90, 89, 35, 81, 48, 33, 94, 81, 76, 86, 67, 70, 100, 80, 83, 78, 96, 58 
Note: m = 71.47 s = 20.98 
Determine the maximum score, the minimum score, the range of scores (maximum – minimum) and a table with column headings:
Grade
Number of scores
using the following scoring (where m is the mean, s is the standard deviation, and x is an individual score):
A 
: 
m+ 4/3 s 
<= x 

A– 
: 
m+ 3/3 s 
<= x < 
m+ 4/3 s 
B+ 
: 
m+ 2/3 s 
<= x < 
m+ 3/3 s 
B 
: 
m+ 1/3 s 
<= x < 
m+ 2/3 s 
B– 
: 
m+ 0/3 s 
<= x < 
m+ 1/3 s 
C+ 
: 
m– 1/3 s 
<= x < 
m+ 0/3 s 
C 
: 
m– 2/3 s 
<= x < 
m– 1/3 s 
C– 
: 
m– 3/3 s 
<= x < 
m– 2/3 s 
D+ 
: 
m– 4/3 s 
<= x < 
m– 3/3 s 
D 
: 
m– 5/3 s 
<= x < 
m– 4/3 s 
F 
: 
x < 
m– 5/3 s 
Place the output in a file, in an orderly format, and inform the user of the name of the file before exiting.
