Can I get this to loop back?

05-06-2002, 02:47 PM

I need to use a for loop so that the program will let the user play Tic Tac Toe 3 times, problem is, once somebody wins, the program continues to ask for moves until somebody breaks the program. Is there anything that will stop the current game, but still take it back to the beginning of the for loop so that the second game can begin?

Thanks for reading.

Try something like this:

Code:

for (i = 0; i < MAX; i++)
{
    ...

    if (restart)
    {
        i = 0;
    }

    ...
}

Yes there is ,add a "i < 3;" To line 28 in your code.

This is the for loop right now... in 'checkforwin' if somebody wins 'win' will equal 1, to stop the while loop, so I'm trying to find a way to get it out of the while loop, and back to the beginning of the for loop.

for (game = 0; game < 4; game = game + 1);
{

clrscr();
board(300,80);

while(win == 0)
{
xmove();
checkforwin();
omove();
checkforwin();

}
}

I managed to get it top stop asking for moves after somebody has won, but the program will exit, instead of going back to the to the beginning of the for loop..

for (game = 0; game < 4; game = game + 1);
{

board(300,80);

while (win < 1)
{
xmove();
checkforwin();

if (win < 1)
{
omove();
checkforwin();
}
}

}

What are you calling to make the prog exit? Is it return or exit()? If so, you need to re-think how that works.

If you get stuck, post a snippet of real code here, and don't forget to use code tags when doing so please.

The basics in your psuedo code look OK to me, so you can't be far off the mark.

I'm using return to close the whole program...
Here's the checkforwin function with the main again:

Code:

void checkforwin()		//Checks if either team has won.
{
	// X's win.
	if( (square1==1 && square2==1 && square3==1) || (square4==1 && square5==1 && square6==1) || (square7==1 && square8==1 && square9==1) )  //Horizontal 

wins.
	{
		printf("Tic Tac Toe! The X's win! X-cellent job! \n");
		player1win = player1win + 1;
		win = win + 1;
	
	}
	if( (square1==1 && square4==1 && square7==1) || (square2==1 && square5==1 && square8==1) || (square3==1 && square6==1 && square9==1) )  //Vertical 

wins.
	{
		printf("Tic Tac Toe! The X's win! X-cellant job! \n");
		player1win = player1win + 1;
		win = win + 1;
	}
	if( (square1==1 && square5==1 && square9==1) || (square3==1 && square5==1 && square7==1) )  //Diagonal Wins.
	{
		printf("Tic Tac Toe! The X's win! X-cellant job! \n");
		player1win = player1win + 1;
		win = win + 1;
	}
	
	// O's win.
	if( (square1==2 && square2==2 && square3==2) || (square4==2 && square5==2 && square6==2) || (square7==2 && square8==2 && square9==2) ) //Horizontal 

wins.
	{
		printf("Tic Tac Toe! The O's win! Neat-O job! \n");
		player2win = player2win + 1;
		win = win + 1;
	}
	if( (square1==2 && square4==2 && square7==2) || (square2==2 && square5==2 && square8==2) || (square3==2 && square6==2 && square9==2) )  //Vertical 

wins.
	{
		printf("Tic Tac Toe! The O's win! Neat-O job! \n");
		player2win = player2win + 1;
		win = win + 1;
	}
	if( (square1==2 && square5==2 && square9==2) || (square3==2 && square5==2 && square7==2) )  //Diagonal Wins
	{
		printf("Tic Tac Toe! The O's win! Neat-O job! \n");
		player2win = player2win + 1;
		win = win + 1;
	}

	// Cat's Game.
	if ((square1 != 0 && square2 != 0) && (square3 != 0) && (square4 != 0) && (square5 != 0) && (square6 != 0) && (square7 != 0) && (square8 != 0) && 

(square9 != 0) && (win == 0))
	{
		printf("Cat's Game! X's and O's are tied! \n");
		win = win + 1;
	}


}
int main()
{
	int gdriver = DETECT, gmode;  		//Determines graphics driver and mode to use.
	initgraph(&gdriver, &gmode, " ");  	//Switches to graphics mode.

        player1win = 0;
	player2win = 0; 
	gamecount = 1;

	for (game = 0; game <= 3; game = game + 1);	//Tic Tac Toe is played 3 times.
	{
		
		win = 0;
		square1 = 0;
		square2 = 0;
		square3 = 0;
		square4 = 0;
		square5 = 0;
		square6 = 0;
		square7 = 0;
		square8 = 0;
		square9 = 0;

		board(300,80);

		printf("\n \n \n \n \n \n \n");
		printf("GAME %d \n", gamecount);

		while (win < 1)
		{
			xmove();
                    	                checkforwin();
			
			if (win < 1)
			{
				omove();
				checkforwin();
			}
		}
			
	}

getchar();
return(0);
}

I just found this out, my for loop works fine without graphics...
The 'xmove' , 'omove' and 'board' are all graphics, does that affect the for loop?

Can't tell without actually knowing what they're doing! Suggest you read through them looking for exit() type functions. If they're not too big, post the source here and someone might help you.
