Thread: error

When i use

Code:

nth_next_game(x, gamestate[9]);

I get this error;

Code:

C:\Program Files\Microsoft Visual Studio\MyProjects\Tic Tac Toe\MichaelNeill.cpp(131) : error C2664: 'nth_next_game' : cannot convert parameter 2 from 'int' to 'int []'

Any know whats wrong with it. Here is my code.

Code:
