Class - Not Recognizing Constructor

This is a discussion on Class - Not Recognizing Constructor within the C++ Programming forums, part of the General Programming Boards category; I have the following in my Board.h file: Code: class CBoard { public: CBoard(); ~CBoard(); int ReturnTile(int X, int Y); ...

    Question Class - Not Recognizing Constructor

    I have the following in my Board.h file:
    Code:
    class CBoard
    {
    public:
    	CBoard();
    	~CBoard();
    	int ReturnTile(int X, int Y);
    protected:
    	int Grid[20][20];
    };
    Now, when I go to Board.cpp, after including the above .h file, and I type "CBoard::", the pop-up menu that appears only contains: Grid, ReturnTile, and ~CBoard. But no Constructor.

    When I try to run the program, I get the error:
    error C2228: left of '.ReturnTile' must have class/struct/union type

    For the following code (Indicated at the *s):
    Code:
    	CBoard MyBoard();
    
    	int TileReturn;
    	for (int XX = 0; XX <= 20; XX++)
    	{
    		for (int YY = 0; YY <= 20; YY++);
    		{
    			TileReturn = MyBoard.ReturnTile(XX, YY); //*****************
    		}
    	}
    And incase you're wondering, all that the ReturnTile code is:
    Code:
    int CBoard::ReturnTile(int X, int Y)
    {
    	return Grid[X][Y];
    }
    But again, I think this all links back to the constructor and it not being recognized. But if you see something else that's causing the problem, I'm all ears
    Thanks for reading.

    Did you actually write a constructor? Just because the popmenu doesn't show it doesn't mean you can't type it out yourself

    >CBoard MyBoard();
    That's not an object, it's a function called MyBoard returning a Cboard object. Remove the parentheses and it might work better for you.

    >for (int XX = 0; XX <= 20; XX++)
    This would be a buffer overflow. You want your loops to look like this:
    Code:
    for (int XX = 0; XX < 20; XX++)
    The same goes for your YY loop too.

    >for (int YY = 0; YY <= 20; YY++);
    Do you see the semicolon there at the end? It means your code is broken. This loop won't do much at all as it is, so you should remove the semicolon.
    My best code is written with the delete key.

    Thanks, I changed around the For Loops, and yes, I did write out the constructor, but your question made me look a bit closer and I had:
    Code:
    CBoard::CBoard();
    {
    //Insert Code
    }
    With a ";" After it. Which, as lots of you would probably point it, doesn't belong there It's all running smoothly now Thanks for the help.
