Passing 2D Array from one function to another?

[Elarionus]

So I'm trying to create a minesweeper game (but with gophers), and I have a function that creates a table and then another function that prints the table. The problem is, once I create the table, I don't know how to get the array to the other function to print the array. Is there a way I can return it? Thanks!

#include <iostream>
#include <time.h>

using namespace std;


//-----Global Variables-----//
const int ROWS = 21;
const int COLS = 21;


//-----Function Prototypes-----//
void rules();

void random_gopher();

void create_field();
void print_field(char arr[][COLS]);
void game();





//-----MAIN FUNCTION-----//
int main()
{
	rules();
	create_field();
	print_field(field);
	return 0;
}



//-----Other Functions-----//
void rules()
{
	cout << "Welcome to gopher hunt!\n\nTo play, enter an X value to pick a row and a Y value to pick a column.\n\n";
}

void create_field()
{
	cout << "Generating field...\n\n";
	char field[ROWS][COLS];
	for (int i = 0; i < ROWS; i++)
	{
		for (int j = 0; j < COLS; j++)
		{
			field[i][j] = '+';
		}
	}
}

void print_field(char field[ROWS][COLS])
{
	for (int i = 0; i < ROWS; i++)
	{
		for (int j = 0; j < COLS; j++)
		{
			cout << field[i][j];
		}
	}
}

The game field should be a public object. For your purposes, that probably means that it should be a global.
