Subscript requires array or pointer type

[CpluspProgrammer]

Hello everyone,
I could really use your help. I am confused about this error that I'm getting. I reread the chapter on pointers and arrays, but I'm still lost. error c2109 subscript requires array or pointer type. Here's my code:

  int GameBoard::turn(int &playerTurn, int position)
{
	char * pBoard = &board[ROW][COL];
	for (int i = 0; i < ROW; i++)
	{
		for (int j = 0; j < COL; j++)
		{
			if (playerTurn == 1)
			{
				if (position >= 1 && position <= 3)
				{
					*pBoard[0][position-1] == PLAYER_ONE;
					playerTurn = 2;
				}
				else if (position >= 4 && position <= 6)
				{

				}
				else if (position >= 7 && position <= 9)
				{

				}
			}
		}
	}

	return playerTurn;
}

You do use subscript operators on lines 3 and 12. Which one has the error? (That information is part of the error message. Do not ignore it.)


At the bottom of http://www.cplusplus.com/doc/tutorial/operators/
is an operator precedence table. The subscript has higher precedence than the dereference operator.

On line 12 you do write:

*foo[x][y]

// which is same as
*( (foo[x])[y] )

// However, the type of foo is char*
// Therefore, the type of foo[x] is char 

Obviously, you cannot use subscript with a char.

You can reproduce the C2109 with:

int main() {
  char bar = 'h';
  int y = 7;
  bar[y]; // C2109
  return 0;
}

PS. What is the difference between = and == ? (Line 12)

The c2109 error is on line 12. I also just noticed the typo on line 12, and fixed it. I guess I'm a little confused on char arrays, I'll read up in my book and reply back later with more questions.
