HELP!! Lost on homework and need a tutor. I don't want you to do my homework I just want to be able to do it

It's either me or my teacher but I am just not getting this stuff. Can someone tutor me on this? I am lost and have no help.

Write a function called delete_repeats that has a partially filled array of characters as a formal parameter
and that deletes all repeated letters from the array. Since a partially filled array requires two arguments,
the function will actually have two formal parameters: an array parameter and a formal parameter of type int
that give the number of array positions used. When a letter is deleted, the remaining letters are moved forward
to fill the gap. This will create empty positions at the end of the array so that less of the array is used.
Since the formal parameter is a partially filled array, a second formal parameter of type int will tell you how
how many array positions are filled. The second formal parameter will be a call-by-reference parameter and will
be changed to show how much of the array is used after the repeated letters are removed.

dogsafire,
I haven't got far. We just got this and didn't get much info. I am in a C++ programing class and the teacher just reads from power point. Last semester only two people passed, now I see why.
I have the highest score in the class and stll don't know what the heck I am doing till we are about 3 weeks past it.

This is our first assn in arrays, we are using Walter Savitch's 6th Edition. I am just trying to get started on this prob. I am having a hard time understanding how to translate the prob into:
const int MAX = 10;
void outputA (int a[], int size);
int main () {
int a[MAX];
int i;
int x;
for (i=0;i<MAX;i++)
a[i]=0;
cout << "Input grades ending with -1 "; // Has to be an int for this situation like(-1)
cin >> x;
i = 0;
while (x>=0 && i<MAX){
a[i] = x;
i++;
cout << "next: ";
cin >> x;}
for (i=0;i<MAX;i++)
cout << a[i] << endl;return 0;
outputA(a,i);
}
void outputA (int a[], int size){
int i;
for (i=0;i<size;i++)
cout << a[i] << endl;
}

How much of this do you have done?
What language are you using (I'm guessing C or C++, but you don't say)?
What portions of the problem statement don't you understand?

Edit:

Man, I hate the way that Yahoo removes indenting!
I'll have to copy for work and put it into an editor so that I can read it more easily.

But what you have written so far only gathers input and doesn't address the function described in the problem. I don't have the book that you reference, but this is a pretty easy problem, so that shouldn't be an issue.

You are instructed to create a function named delete_repeats.
The function will accept an array of characters to operate on and an integer that tells how many entries exist in the array. The integer must be passed by reference so that its value can be changed within the function.

The function's job is to search through the array of characters looking for repeated characters. If it finds one, it removes it, shifts the remaining array entries forward, and decrements the count of the number of characters in the array.

So, to start with, can you write the function declaration?
