** C++ must be used. ensure prototypes are used by the main function **

Write a Gradebook program with the following functionality.

Reads in from the keyboard the input for four students

Full Name

Student ID - a 7 digit number (no need to validate for exactly 7 digits, use an int)

Scores[5] - an array holding five test scores

Drop the high score and the low score. Average the remaining scores

Assign a letter grade based on the average score for the student

Calculate the class average based on each student's 3 middle scores (the average of the student averages).

Display in a table format each students' name, five test scores, average, and letter grade

Display the class average

BONUS (5 points): Find the student with the highest average and display that student's name, ID, and average

BONUS (5 points): Read in the data from an input file and include the .txt file with your submission

Design your solution to use structs, functions, arrays, and only 2 global constants.

Helpful Hints:

You may use NUM_STUDENTS = 4 and NUM_TESTS = 5 for global constants

Create a Student struct with the following members

name

ID

scores[NUM_TESTS]

average

grade

Add the Student struct to global space (not in a header file)

Create an array of structs (one element for each student),

for example, Student CIS5[NUM_STUDENTS]

When utilizing a nested loop with an array of structs and a member array, be careful how you use the subscriptsfor example, the syntax for identifying a specific test for a specific student looks like this

CIS5[i].scores[j] // use dot notation to access member data in a struct

where i is the subscript for the specific student and j is the subscript for the specific test

Use good design, good style, and efficient logic (no brute force logic)
