Create a program to calculate grades as well as descriptive statistics for a set of test scores. The
test scores can be entered via a user prompt or through an external file. For each student, you need
to provide a student name (string) and a test score (float).
The program will do the followings:
• Assign a grade (A, B, C, D, or F) based on a student's test score.
• Display the grade roster as shown below:
Name
Test Score
Ann
John
Karen
90
100
93
o Average score
o Maximum score
o Minimum score
Grade
=====
AAA
A

A
Calculate the following descriptive statistics (as shown below)
o Number of students in the class
================Class Statistics ==
Number of students in the class: 3
Class Average: 94.3333
Maximum Test Score: 100
Minimum Test Score: 90
The program must use
o A loop structure (for-loop, while-loop, or do-while-loop)
o Conditional processing (if-then-else)
o Arrays or vectors
