hi all,im new here and im a beginner at c++, im making a simple tic tac toe program, and its not working properly, it cant determine the winner,could someone please help.

heres the code

```
#include<iostream.h>
#include<conio.h>
#include<stdlib.h>
#include<stdio.h>
#include<graphics.h>
#include<ctype.h>

case 'N':exit(0);
}
}
getch();
}
```

also i wasnt able to use graphics to draw a grid, could someone please tell how to do that.im using turbo C++,also if someone could give a simpler code for determing the winner or draw match,it would be very helpful.

thank you
