HELP!! Doing project using arrays

[afrocoder]

I'm working on a project for my introductory class using arrays. The project asks the following:
You have 10 students.

1. Get each student's score (0 - 100). Validate the scores.

2. Display each student's ID (1 - 10) and their grade.

3. Display sum of all grades and average at the end in nice table format.

4. You must use arrays to store student IDs and student grades.

5. At last, count how many students are in each grade ranges (< 50, 50s, 60s, 70s, 80s, 90s) and display the results.

6. You must use functions passing the arrays to calculate the Sum and Average.

7. Use a function for task 5.

8. Use a function to read grades.

I've been struggling with C++ as a whole and would greatly appreciate any help or guidance. Here's all I have so far though its pretty sad:
#include <iostream>
#include <iomanip>
#include <time>
#include <cstdlib>
using namespace std;

int main()
{
int studentGrades[10]


}

Welcome!
Well do you know how to use for loops?
And what do you mean by "Display each student's ID (1 - 10) and their grade.". What is grade? A letter?
arrays to store student IDs Isnt ID from 1-10? Why to use an array to store the numbers 1 to 10?

Hello.
I get the basics of the for loop. By grades its asking for the user to input numerical values. As for the student ID I think that is just the natural array order but not entirely sure. I care more about completing and understanding the project as a whole and will worry about that part after.
