Thread: using objects and pointers

Hello,

I am re-engineering someone elses code and have come across some code I don't really understand.

To keep it simple I have just displayed the code snippets.

I have a class called Board

Code:

class Board
{
	private:
	Board *_boards[10];

	public:
	Board* const* boards() const; 
.
.
.
};

Board* const* Board::boards() const
{
	return _boards;
}

Now I have another a cpp file that using this class.
I have this code which I find hard to understand.

Code:

Board *board = static_cast<Board*>(boards()[i]);

I don't know why there is a [i] at the end of the boards() function?

Any advice would be most gratefull,

Thanks,

Hello,

Thanks for the response.

So that this is really doing is:

Code:

(*boards()  + i))

dereferencing and returning the board pointer object?

However, just one more question.

I have a member of that class. Called _boardID which is public. However, should be private for for testing purposes I have it as public.

But I can't seem to access using the index:

Code:

board[0]._boardID = 1001;

However, I can do this:

Code:

board->_boardID = 1001;

I thought I should be able to access using both methods. However, the first one is needed as I need direct access to some elements.

Any thoughts about this?

Many thanks,
