Thread: need help with source

Ok im having trouble with my Tic-Tac-Toe program. I am currently working on the part where the computer reads what move the user did and then moves according to the rules. Now I havn't wrote all of the computers rules yet because I dont know if this is how to do it. When I try to run the program it messes up. Here is the source. I hope Yall can find the problem.

Code:

#include <iostream>
#include <fstream>
#include <string>


using namespace std;

int x=1;
int o=2;
void startgame();
void xturn();
void oturn();

int moves[9] = {1,2,3,4,5,6,7,8,9};


	int main()
	{

		int xx;

		cout << "Would you like to play a game of Tic-Tac-Toe?" << endl;
		cout << "1 for yes, and 2 for no" << endl;

		cin >> xx;

		 if (xx == 1)
		     startgame();
		 else
			 if ( xx == 2)
			  cout << "Looseer!!!!" << endl;

			 return 0;

	}


	void startgame()
	{

		int win = 0;
		int count = 0;
		int victory = 0;
		int mover;

		cout << "Lets play." <<  endl;

		cout << "You are X. Press 1-9 to make a move." << endl;


		for ( count=1; count<=9; count++)
		{
			moves[9] = count;

			// This part of the code is used to deturmine whos move it is.
			if (moves[1] != false)
				xturn();
			if (moves[2] != false)
				oturn();
			if (moves[3] != false)
				xturn();
			if (moves[4] != false)
				oturn();
			if (moves[5] != false)
				xturn();
			if (moves[6] != false)
				oturn();
			if (moves[7] != false)
				xturn();
			if (moves[8] != false)
				oturn();
			if (moves[9] != false)
				xturn();

			if (count==9)
			{
				if (!victory)
					cout << "DRAW!!" << endl;
				else
					if (victory != false)
						cout << mover << " WINS!!" << endl;
			}
		}

	}

	void xturn()
	{
		cin >> x;

		cout << "You moved to square " << x;
		cout << endl;
	}

	void oturn()
	{
		
		if (x==1)
		{
			o==5;
		}
		else
			if (x==5)
				o==1;

		cout << "The computer moved to square " << o;
		cout << endl;
	}

Yes i know that arrays start at 0 but when I plug in 0 then the for loop goes 10 times and there is only a maximum of 9 moves in tic tac toe. I guess I can change that 9 to an 8. But do u think the code i used to check to see whos turn it is will work? If not any suggestions?

Well dud there is only one problem with that code. The while loop will always continue. I would fix it to where gameover checks to see if any one won or if there was a draw. But I do no know how to do this. Can I do it like this?

Code:

bool gameOver=false;

//then later on down

bool gameOver
{
   for (count=0; count <=8; count++)
   {
     if (moves[x] == 1 && moves[x] == 2 && moves[x] == 3)
        win;
    }
}

Will something like that work? If not how can I do this?

Ok I figured out that last question on my own. But now I have anouther. Ok I wrote some code that will check if the square is taken; like so

Code:

void square(int player)
	{

		if (player==1)
			cout << "Cannot move there Square taken!" << endl;
		else
		if (player==2)
			cout << "Cannot move there Square taken!" << endl;
		else
		if (player==3)
			cout << "Cannot move there Square taken!" << endl;
		else
		if (player==4)
			cout << "Cannot move there Square taken!" << endl;
		else
		if (player==5)
			cout << "Cannot move there Square taken!" << endl;
		else
		if (player==6)
			cout << "Cannot move there Square taken!" << endl;
		else
		if (player==7)
			cout << "Cannot move there Square taken!" << endl;
		else
		if (player==8)
			cout << "Cannot move there Square taken!" << endl;
		else
		if (player==9)
			cout << "Cannot move there Square taken!" << endl;
	}

Basically it checks every square to see if the player took it or not. But I am unable to install it. Where do yall think should I put it? My source is above. Thanx

well fry u see that part of the game doesnt crash. What im trying to do is figure out how to make the gameOver variable work in such a way that it detects who won and detects if the moves have exceded 9. Iv got the game to end after 9 moves. That was easy. I know how to check to see if there is a winner but how can i use it in a while(!gameOver) loop? Can I juz plug it in there or what? Here is my code.

Code:

while (!gameOver)
			{

				count++;

				  if(count==9)
				  {
					gameOver=true;
				  }

				 if (xturn)  
					 x_turn();
				 else        
					 o_turn();
				 xturn = !xturn; // flip xturn
				 // check for gameOver
			}
	}

O and do you guys think that this code will work (used in the right place) to detect weather someone has moved there?

Code:

void square(int player)
	{

		if (player==1)
			cout << "Cannot move there Square taken!" << endl;
		else
		if (player==2)
			cout << "Cannot move there Square taken!" << endl;
		else
		if (player==3)
			cout << "Cannot move there Square taken!" << endl;
		else
		if (player==4)
			cout << "Cannot move there Square taken!" << endl;
		else
		if (player==5)
			cout << "Cannot move there Square taken!" << endl;
		else
		if (player==6)
			cout << "Cannot move there Square taken!" << endl;
		else
		if (player==7)
			cout << "Cannot move there Square taken!" << endl;
		else
		if (player==8)
			cout << "Cannot move there Square taken!" << endl;
		else
		if (player==9)
			cout << "Cannot move there Square taken!" << endl;
	}

I think it should work. If not any suggestions?

Hey guys. Im trying somthing new. Im trying to take an array called board and use that as the tic tac toe board. And then im using an array called moves for the x's and o's. Now when I compile this code and run it. All I get back from the computer is 0. So one of my questions is did I set up the board right? Moves[x]==board[x] does that tell the board that the square inputted by x is taken? If not how can I do it?

If my first question is answered then I can probley figure out my second one.

Code:

void x_turn()
	{

		moves[0,2,4,6,8]=x;

		cin >> x;

		moves[x]==board[x];

		cout << "You moved to square " << x;
		cout << endl;

		if (moves[x] > 9)
		{
			cout << "You may not move there"; 
		    gameOver=true;
		    cout << endl;
			cout << "GAME OVER!" << endl;
		}
	}

	void o_turn()
	{

		moves[1,3,5,7]=o;

		int count=1;

				if (board[x]==5)
					moves[o]=1;
				else
					if (board[x]==1)
						moves[o]=5;	

		//if (x == corner)
		//	o=2;


		cout << o;
		cout << endl;
	}
