C++ Array parameters and const value - c++

Question

I do not get arrays, Im sure there are easier ways to make this program but I must do it the teacher's way and I am lost.
This is the assigment:
I do not get how I should go about these arrays. most confusing thing I seen by far.
What I would like is a guide or help on how i should program these arrays or how I should program arrays period. Not asking to do the rest for me, I already know how to do most of this, its just the arrays I like to know how to do.
This is my current program:
#include<iostream>
using namespace std;
void getPoints(int pPossible[], double pEarned[], int numItems, int limit);
int sumArray(double
void getpoints(int pPossible[], double pEarned[], int numItems, int limit)
{
int count;
while (limit == limit)
{
cout << "Input grade points for a category in the gradebook: " << endl
<< "How many items available in the category?: ";
cin >> numItems;
cout << endl;
if(numbItems > limit)
{
cout << "The Value exceeds the maximum number of items." << endl;
continue;
}
break;
}
count=1;
for(count=1; count<numItems; count++)
cout << "Enter points then points possible for Item " << count << ": ";
cin << pEarned[count] << pPossible[count];
return 0;
}

C++ array indexes are zero-based, so you should use zero for the initial value in the for loop. Also, you're missing the braces for the for loop body; as it is, it will run the cout line numItem-1 times and the cin line just once.
Another thing: the operators in the for's cin line should be >>, not <<. You want input here, not output.
Finally, like #ebyrob said, make numItems a reference parameter (it would be clearer for the caller to use a pointer instead, but the assignment asked for a reference parameter).
void getpoints(int pPossible[], double pEarned[], int& numItems, int limit)
{
//Read number of items
while (true)
{
cout << "Input grade points for a category in the gradebook: " << endl
<< "How many items available in the category?: ";
cin >> numItems;
cout << endl;
if(numItems >= limit)
{
cout << "The Value exceeds the maximum number of items." << endl;
continue;
}
break;
}
//Read earned and possible for each item
for(int count=0; count<numItems; count++)
{
cout << "Enter points then points possible for Item " << count << ": ";
cin >> pEarned[count] >> pPossible[count];
}
return 0;
}
