    Passing 2d Array to function?

    I am triying to pass a 2d Array to a function, but I dont know how, can someone help? here is my code:
    Code:
    #include <iostream>
    using namespace std;
    
    void PrintBoard(int* TheBoard, int Rows, int Columns); 
    
    int main()
    {
    	int Board[5][5];
    	int i = 0, j = 0;
    
    	for (i = 0; i < 5; i++)
    	{
    		for (j = 0; j < 5; j++)
    			Board[i][j] = '\0';
    	}
    
    	Board[2][2] = 5;
    
    	PrintBoard(Board, 5, 5);
    
    	return 0;
    }
    
    void PrintBoard(int* TheBoard, int Rows, int Columns)
    {
    	int i = 0, j = 0;
    
    	for (i = 0; i < Rows; i++)
    	{
    		for (j = 0; j < Columns; j++)
    			cout << TheBoard[i][j];
    		cout << endl;
    	}
    }
    Thanks in advance.

    Code:
    void PrintBoard(int board[][],int row,int collum)
    {
    bla
    bla
    bla
    }
    Would that work for ya?

    like salem said..that wont work, it shouldnt even compile if memory serves

    but this should...
    Code:
    void PrintBoard(int board[][5],int row,int collum)
    {
        /* Code */    
    }
    as long as you define the number of colums so the compiler knows whats going on.....otherwise the compiler doesnt know how to map out your array

    i didnt either until i got it wrong on a test, and i was trying to explain to the teacher why i put what i put, and he said all that needs to be defined is the colums...simply for the reason, if you had a 1 dimensional array....thats all you have, columns
