Need some assistance with a little c++ game

[|Show|]

Right, well i'm making a simple game in c++

The grid

You move the mouse (the '@') around the grid and the idea is that you have to 'push' the 'apples' ('o's) into the 'store' (+ area)

The mouse and apple positions are stored in two arrays -

void setInitialAppleCoordinates( int apple[6][2])
{
int matrix[6][2] = {{8, 3},
		          {3, 6},
			  {5, 6},
		          {8, 6},
			  {4, 8},
			  {5, 8} };
for ( int row( 0); row <= 5; ++row)			 //for each row (vertically)
		for ( int col( 0); col <= 1; ++col)      //for each column (horizontally)
			apple[row][col] = matrix[row][col];

}

void setInitialMouseCoordinates( int mouse[])
{ //calculate mouse's coordinates at beginning of game
	mouse[0] = 9;                                          //y-coordinate: vertically
	mouse[1] = 15;                                        //x-coordinate: horizontally
}

Then the following is used to 'move' the mouse, and soon apples -

void moveMouse( const char grid[][ SIZEX+1], int mouse[], int key, string& mess, int& moves)
{ //move mouse in required direction
	bool setKeyDirection( int key, int& DX, int& DY);
	int DX( 0), DY( 0);
	//find direction indicated by key
	bool isArrowKey = setKeyDirection( key, DX, DY);
	if ( ! isArrowKey)                                          //key is not an arrow
		mess = "INVALID KEY!";
	//check new target position in grid & update mouse coordinates if move   possible
	switch( grid[mouse[0]+DY][mouse[1]+DX])
	{			//...depending on what's on the target position in grid...
		case TUNNEL:	//can move
			mouse[0] += DY;                                  //go in that Y direction
			mouse[1] += DX;                                  //go in that X direction
			moves++;
			break;
		case STORE:	//can move
			mouse[0] += DY;                                  //go in that Y direction
			mouse[1] += DX;                                  //go in that X direction
			moves++;
			break;
		case WALL: //can't move                             //hit a wall & stay there
			cout << '\a';                                            //beep the alarm
			mess = "CANNOT GO THERE!";
			break;
	}
}

now, can anyone suggest a simple way of adding a case of APPLE to get the apple character to move with the mouse?

thanks
