2D Arrays.

[Nahjil567]

So my book provided me with a function prototype.
void printTable(int rows, int cols, TwoDimArray aTable);
Where the TwoDimArray is
typedef int TwoDimArray[NUM_ROWS][NUM_COLUMNS];
The constants for the indices are 15.
When my program tries to call a matrix variable of this type it errors out.
I have tried telling the function the size of the NUM_COLUMNS. I'm getting a little frustrated. Here is what my code looks like at the moment.

#include <iostream>
#include <iomanip>
using namespace std;

const int NUM_ROWS = 15;
const int NUM_COLUMNS = 15;

typedef int TwoDimArray[NUM_ROWS][NUM_COLUMNS];

void populateMatrix (int rows, int cols, TwoDimArray **aTable);
void printTable(int rows, int cols, TwoDimArray **aTable);

int main()
{
    int rows = 1, columns = 1;

    cout <<"Please enter the number of rows: ";
    cin >> rows;
    cout << "\nPlease enter the number of columns: ";
    cin >> columns;

    TwoDimArray aTable[rows][columns];

    populateMatrix(rows, columns, aTable);
    printTable(rows, columns, aTable);
    return 0;
}

void populateMatrix (int rows, int cols, TwoDimArray aTable[][15])
{

for(int i = 0; i < rows; i++)
        for(int j = 0; j < cols; j++)
        {
            cout << "Please enter the aTable[" << i << "] ["<< j <<"]:";
            cin >> aTable[i][j];
            cout << endl;
        }
}

Thank you for any help.

// your book gave you this:
void printTable(int rows, int cols, TwoDimArray aTable);

// you are doing this:
void printTable(int rows, int cols, TwoDimArray **aTable);

Why did you make it a pointer to a pointer to a 2D array?

I was attempting to get it to pass several different manners, then forgot to clean up before I posted, but I have it figured out now. I'm an idiot. The error happens at line 22. It isn't necessary. Well the declaration is, but the rows, and cols are not.
