Thread: Tic-tac-toe using mouse

Hi,
I am new to this forum.I was just trying to do a tic tac toe game using mouse,but i am facing some wierd problem.I was trying to do like this,on a left button click i should get "x",then on the next click i should get "o",but the combination is not right.Here is the code:

Code:

#include<graphics.h>
#include<conio.h>
#include<dos.h>
#include<stdio.h>
#include<stdlib.h>

void init_mouse();
void show_mouse();
int lb_prs();
void get_coord(int *,int *);
void hidemouse();
int chk_coord(int *,int *);

int board_fill[3][3]={0,0,0,0,0,0,0,0,0};

int main()
{
int gdriver=DETECT,gmode;
initgraph(&gdriver,&gmode,"c:\\tc\\bgi");
int x1,y1,x2,y2,i,j,but1=0,but2=0,p,q,turn=0;
char ch;

choose_menu();
getch();
cleardevice();

x1=0;
y1=0;
x2=0;
y2=0;
i=0;
j=0;

cleardevice();

setlinestyle(0,3,3);
line(210,200,390,200);
line(210,260,390,260);
line(270,140,270,320);
line(330,140,330,320);

init_mouse();
show_mouse();

setcolor(3);

while(turn<9)
{

a:
x1=0;
y1=0;
i=0;

if(lb_prs())
	{
	get_coord(&x1,&y1);
	i=chk_coord(&x1,&y1);
	while(lb_prs());
	if(i==1)
		{
		hidemouse();
		settextstyle(0,0,3);
		outtextxy(x1,y1,"X");
		show_mouse();
		turn++;
		}
	else
		{
		outtextxy(0,0,"Wrong input..");
		goto a;
		}
}

b:
x1=0;
y1=0;
i=0;

if(lb_prs())
	{
	get_coord(&x1,&y1);
	i=chk_coord(&x1,&y1);
	while(lb_prs());
	if(i==1)
		{
		hidemouse();
		settextstyle(0,0,3);
		outtextxy(x1,y1,"O");
		show_mouse();
		turn++;
		}
	else
		{
		outtextxy(0,0,"Wrong input..");
		goto b;
		}
	}

}
