Thread: TTT Problem

Here I have a ttt code:

Code:

#include <stdio.h>
#include <windows.h>

int turn, move;
char name1[25], name2[25];
char board [9]; // The tic-tac-toe Board


void DrawBoard();
void DrawBoard() //* Draws the board *//
{
printf("\n\n");
printf(" %c | %c | %c \n", board[1], board[2], board[3]);
printf(" --------- \n");
printf(" %c | %c | %c \n", board[4], board[5], board[6]);
printf(" --------- \n");
printf(" %c | %c | %c \n", board[7], board[8], board[9]);
printf("\n\n");
}

void CheckSpace(); 
void CheckSpace() // Checks for double usage and places X's and O's
{
	if (turn == 1)
	{board[move] = 'X';}
else
	{board[move] = 'O';}
}


int main()

{
BOOL StillPlaying=TRUE;
int move=0;
int turn=1;

printf("Welcome to tic-tac-toe!!!\n\n");

//players names
printf("What is player 1's name: ");	
	scanf("%s", name1);
printf("\nWhat is player 2's name: ");
	scanf("%s", name2);
	
while (StillPlaying)
	{
		DrawBoard();

	if (turn == 1){
		printf("Please make a move %s : ", name1);
		scanf("%d", &move);
		turn=2;
		printf("\n");
		}
	else{
		printf("Please make a move %s : ", name2);
		scanf("%d", &move);
		turn=1;
		printf("\n");
	} 

	
CheckSpace();

}//While Winner

return 0;	

}// int main()

When I put the piece of code which assigns X's and O's in a function it seems to to see it or read it right. If I move the code in the while loop its okay.. Why is that

Well look at this... Its same code but I moved the X and O assign code in the while loop:

Code:

#include <stdio.h>
#include <windows.h>

int turn, move;
char name1[25], name2[25];
char board [9]; // The tic-tac-toe Board


void DrawBoard();
void DrawBoard() //* Draws the board *//
{
printf("\n\n");
printf(" %c | %c | %c \n", board[1], board[2], board[3]);
printf(" --------- \n");
printf(" %c | %c | %c \n", board[4], board[5], board[6]);
printf(" --------- \n");
printf(" %c | %c | %c \n", board[7], board[8], board[9]);
printf("\n\n");
}

void CheckSpace(); 
void CheckSpace() // Checks for double usage and places X's and O's
{
}


int main()

{
BOOL StillPlaying=TRUE;
int move=0;
int turn=1;

printf("Welcome to tic-tac-toe!!!\n\n");

//players names
printf("What is player 1's name: ");	
	scanf("%s", name1);
printf("\nWhat is player 2's name: ");
	scanf("%s", name2);
	
while (StillPlaying)
	{
		DrawBoard();

	if (turn == 1){
		printf("Please make a move %s : ", name1);
		scanf("%d", &move);
		turn=2;
		printf("\n");
		}
	else{
		printf("Please make a move %s : ", name2);
		scanf("%d", &move);
		turn=1;
		printf("\n");
	} 

	
{
	if (turn == 1)
	{board[move] = 'X';}
else
	{board[move] = 'O';}
}

}//While Winner

return 0;	

}// int main()

and it works just fine... but why wouldn't it work in a function thing

It doesn't matter if it's unnatural, it's how arrays work in C. Either don't use arrays, or modify the input:

"Enter a value from 1 to 9:"
value_entered: 8

value_entered -= 1;

Quzah.

I am not going to add all that if the compiler i am using and the C language doesn't give me any errors.

Yea i fix the array and assign ' ' to all board spaces
