Thread: what is wrong?

I have a Human class that is derived publicly from a pure Player class.

Player class includes <vector>
Human class includes Player

In the human class i define a function, which is not defined in Player class (this is just a function related to Human class alone... it has nothing to do with Player):

Code:

int  bet(vector<int>& availableBets, HINSTANCE hinstance);

Code:

int Human::bet(vector<int>& availableBets, HINSTANCE hinstance)
{
	//this function should pop up a modal dialog box
	//so that the player can choose his bet

	//get handles to all of the buttons to disable
	//some if needed
	
	

	_bet = (int)DialogBox(hinstance, //application instance
	                  MAKEINTRESOURCE(IDD_ChooseBet), //style
					  0, //parent
					  (DLGPROC)ChooseBetProc //dialog procedure
					  );
}

there is nothing wrong with the implementation but i got these error when compiling:

error C2061: syntax error : identifier 'vector'
error C2062: type 'int' unexpected
error C2143: syntax error : missing ';' before '{'
error C2447: '{' : missing function header (old-style formal list?)


what is wrong?

it worked!!!
strange :S

because in Player class, it has a function that takes a vector reference without an std!!

thnx
