Hello, I need some help with this homework problem for my advanced data structure course. It is all done in c++ but I am mostly still lost with this .h file stuff. I have placed the following assignment below.

No negative value ( -numbers input) can be input, if so the a line must be created and called upon with the explanation as "Invalid value, please enter a correct value"

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
Grade
====
==
!==

100
93
A

A
Calculate the following descriptive statistics (as shown below)
Number of students in the class
o Average score
Maximum score
Minimum score
======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
A loop structure (for-loop, while-loop, or do-while-loop)
Conditional processing (if-then-else)
о Arrays
At least one function
