Thread: question

Can anyone help me. I have a bit of code that i need for my next project (anouther damn tic tac toe project) but I can't seem to get it to work. This is the code my teacher gave in class so its right. All I need to know is how to define the varibles. I tried defining them all differant kinds of ways but i still get error messages. Heres my code. If someone could compile it and tell me how to fix it that would be great.

Code:

#include <iostream>
#include <string>

using namespace std;

bool safe(int);
void nth_nextgame(int,int,int);

	int main ()
	{
		return 0;
	}

	void nth_nextgame (int n, int gamestate[9], int nextgame[9])
	{
		for (int i=0; i<9; i++)
		{
			if (i<number_of_moves(gamestate))
				nextgame[i]=gamestate[i];
			else

			if (i==number_of_moves(gamestate))
				nextgame[i]=nth_nextgame(n,gamestate);
			else
				nextgame[i]=-1;
		}
	}


	bool safe (int gamestate[9])
	{
		//o's move only!!!!!!

		bool safeflag=false;
		num_of_suc=9-number_of_moves(gamestate);
		int nextgame[9];

		if (number_of_moves(gamestate)%2==1)
		{
			for (int i=1; i<=numofsuc; i++)
			{
				nth_nextgame(i, gamestate, nextgame);
				if (safe(nextgame))
					safeflag=true;
			}
		}
		else
		{
			bool safeflag=true;

			if (number_of_moves(gamestate)%2==1)
			{
				for (int i=1; i<=numofsuc; i++)
				{
					nth_nextgame(i, gamestate, nextgame);
					if (!safe(nextgame))
						safeflag=false;
				}
			}
		}
	}
