Write a C++ program that asks user number of students in a class and their names….

Write a C++ program that asks user number of students in a class
and their names. Number of students are limited to 100 maximum.
Then, it will ask for 3 test scores of each student. The program
will calculate the average of test scores for each student and
display with their names. Then, it will sort the averages in
descending order and display the sorted list with students names
and ranking.
Follow the Steps Below

Save the project as A4_StudentRanking_yourname.
Use functions to divide your program into manageable pieces.
Define three functions: displayList,
findAverage, and sort.

Write function prototypes at the top and
define the functions after the main function.

findAverage function:

This function will get 4 parameters: array of student names, 2D
array of grades from 3 tests of each student, array of averages to
fill in, number of students as the arrays size.
You need nested for loop to calculate average of 3 test scores
for each student and record it to the array of averages. (You may
define array of names and 2D array of grades as constants in the
parameter list since you dont need to make any changes.)
No return value needed; changes will apply on the original
array of averages.

displayList function:

This function has 3 parameters: array of student names, array
average scores, and the size of the arrays.
The function doesnt make any changes on the arrays, so define
them as constants in the parameter list.
Call the function twice in your program

When averages are calculated
When averages are sorted

sort function:

This function gets 3 parameters: array of students, array of
averages, and number of students as the size of the arrays.
Use selection sort algorithm. Sort both arrays
based on the average scores in descending order. (You will apply
the sort on the array of averages by comparing the scores, but
apply the swapping on both arrays. They are parallel arrays. This
means they use the same index numbers.)

Define constants as global constants. Do not
use any literal in the program, use their identifiers.
Write function prototypes.
Keep variable definitions local.
At the beginning of the program inform user about the program.
Display a message stating that they can enter 3 test scores and any
number of students limited to 100.
Ask for number of the students to user.
Array of students, test scores, and averages are
parallel arrays. This means they store related
data in the same subscript.
The array of test scores is a two-dimensional array. First
subscript holds number of students and second subscript holds
number of test scores.
Validate user input with a while or do-while loop. They
shouldnt exceed the maximum number; also, it cant be less than
1.
Ask for the student names and their test scores. Use
getline function to get the students full names.
You must use cin.ignore() before using the getline
function since you also use cin object.
Call findAverage function.
Call displayList function.
Call sort function.
Call displayList function.
Use comment lines to describe block of code statements in the
program.
