Need help!!

i just got this problem for an assignment and have no idea how to do it.... can anyone help me!!!!!!!
Problem:
A theatre seating chart is implemented as a two-dimensional array of ticket prices, like this:
10 10 10 10 10 10 10 10 10 10
10 10 10 10 10 10 10 10 10 10
10 10 10 10 10 10 10 10 10 10
10 10 20 20 20 20 20 20 10 10
10 10 20 20 20 20 20 20 10 10
10 10 20 20 20 20 20 20 10 10
20 20 30 30 40 40 30 30 20 20
20 30 30 40 50 50 40 30 30 20
30 40 50 50 50 50 50 50 40 30
Write a program that prompts users to pick either a seat or a price. Mark sold seats by changing the price to 0. When a user specifies a seat, make sure it is available. When a user specifies a price, find any seat with that price starting at the front and working to the back of the theatre. Make sure you write your program using well defined functions.

You are to hand in:
· Source code (well documented)
· Input file (if used)
· Sample user files to test valid and invalid choices
· Hierarchy Chart
· User Guide

I dunno - it's a bit late in the semester for you to start catching up with everyone else. Perhaps just drop the course now.

ohh sorry.. well i have a little bit done but i just cant finish it.. this is what i have
insert

#include <iostream>
#include <iomanip>

using namespace std;

int main ()
{
    int ROWS = 9;
    int ISLES = 10;
    int counts[ROWS][ISLES] =
    {
        { 10, 10, 10, 10, 10, 10, 10, 10, 10, 10 },
        { 10, 10, 10, 10, 10, 10, 10, 10, 10, 10 },
        { 10, 10, 10, 10, 10, 10, 10, 10, 10, 10 },
        { 10, 10, 20, 20, 20, 20, 20, 20, 10, 10 },
        { 10, 10, 20, 20, 20, 20, 20, 20, 10, 10 },
        { 10, 10, 20, 20, 20, 20, 20, 20, 10, 10 },
        { 20, 20, 30, 30, 40, 40, 30, 30, 20, 20 },
        { 20, 30, 30, 40, 50, 50, 40, 30, 30, 20 },
        { 30, 40, 50, 50, 50, 50, 50, 50, 40, 30 },
    };
}

void getdata (const counts[][], int ROW, int ISLE, int pick)
{
    cout<<"Press (1) if you would like to pick a seat and press (2) if you would like to enter a price: "<<endl;
    cin>>pick;

    if (pick == 1)
    {
        cout<<"Please enter the row you would like to sit in: "<<endl;
        cin>>ROW;
        cout<<"Please enter the isle you would like to sit in: "<<endl;
        cin>>ISLE;
    }
    else if (pick ==2)
    {
        cout<<"Please enter the price: "<<endl;
        cin>>price;
    }
}

Your getdata() method doesn't actually do anything, there is no value returned, nor are any of the params non local. I believe you need to modify that method to have a return value representing the chosen tickets price.

Also, you are double creating the 2d matrix. Either move its declaration inside the method, instead of passing it as a param, or pass it by reference ( and an ampersand to the function declaration ).

Finally, don't use all caps for non const/global declarations, this is a pretty universally established convention.

Regardless of what happens in your GetData function, it will never happen at all as you do not call it.
return 0 from main.
This is an oft seen assignment and i think there is a lot of advice in the board history if you care to look, but one tip for you is score extra marks by implementing a file read function to assign the array values, instead of your hardcoded version its an easy win and might help you pick a mark or two up if the rest of your work bombs...the tutor put this as a possibility in your criteria, you should interpret things like that as opportunities to score.
