	I have a problem with passing multi-dimensional arrays to my function. 
Can anyone show me how to pass multi-dimensional arrays to functions?

	The following code always works fine for a single dimensional array, 
but not multi-dim's like the one in the example below (also, see my compiler 
output below that):



#include <iostream.h>

void print_array(int *);

void main()
	{
	int array1[3][3];


	array1[0][0] = 1;
	array1[0][1] = 2;
	array1[0][2] = 3;

	array1[1][0] = 4;
	array1[1][1] = 5;
	array1[1][2] = 6;

	print_array(array1);
	}


void print_array(int * par_array1)
	{
	cout << "array1[0][0]:\t" << par_array1[0][0] << endl;
	cout << "array1[0][1]:\t" << par_array1[0][1] << endl;
	cout << "array1[0][2]:\t" << par_array1[0][2] << endl;

	cout << "array1[1][0]:\t" << par_array1[1][0] << endl;
	cout << "array1[1][1]:\t" << par_array1[1][1] << endl;
	cout << "array1[1][2]:\t" << par_array1[1][2] << endl;
	}



Here's what I get for my compiler errors:

c:\c_progra.ms>gxx testing.cc -o testing.exe
testing.cc: In function `int main(...)':
testing.cc:19: passing `int (*)[3]' as argument 1 of `print array(int *)'
testing.cc: In function `void print_array(int *)':


This one it gives for lines 26-28, 30-32...

testing.cc:26: invalid types `int[int]' for array subscript


						Thanks,
