Problem with my game

Hi im new in this forum and I got some problems with my tic-tca-toe game.

here is the code:

Code:

---

#include <stdio.h>
#include <stdlib.h>

int main()
{
  int i = 0;   
  int player = 0;         
  int go = 0;               
  int row = 0;                   
  int column = 0;         
  int line = 0;                               
  int winner = 0;     
  char board[3][3] = {               
                      {'1','2','3'},     
                      {'4','5','6'},     
                      {'7','8','9'}       
                    };


  for( i = 0; i<9 && winner==0; i++)
  {

    printf("\n\n");
      printf(" %c | %c | %c\n", board[0][0], board[0][1], board[0][2]);
      printf("---+---+---\n");
      printf(" %c | %c | %c\n", board[1][0], board[1][1], board[1][2]);
      printf("---+---+---\n");
      printf(" %c | %c | %c\n", board[2][0], board[2][1], board[2][2]);
     
      player = i%2 + 1;   
 
 
      do
      {
        printf("\nPlayer %d, please enter the number of the square "
      "where you want to place your %c: ", player,(player==1)?'X':'O');
        scanf("%d", &go);

        row = --go/3;                             
        column = go%3;                       
      }while(go<0 || go>9 || board[row][column]>'9');

      board[row][column] = (player == 1) ? 'X' : 'O'; 

     
      if((board[0][0] == board[1][1] && board[0][0] == board[2][2]) ||
        (board[0][2] == board[1][1] && board[0][2] == board[2][0]))
        winner = player;

      else
        for(line = 0; line <= 2; line ++)
          if((board[line][0] == board[line][1] && board[line][0] == board[line][2])||
            (board[0][line] == board[1][line] && board[0][line] == board[2][line]))
            winner = player;
     

  }

  printf("\n\n");
  printf(" %c | %c | %c\n", board[0][0], board[0][1], board[0][2]);
  printf("---+---+---\n");
  printf(" %c | %c | %c\n", board[1][0], board[1][1], board[1][2]);
  printf("---+---+---\n");
  printf(" %c | %c | %c\n", board[2][0], board[2][1], board[2][2]);


  if(winner == 0)
      printf("\nHow boring, it is a draw\n");
  else
      printf("\nCongratulations, player %d, YOU ARE THE WINNER!\n", winner);

return 0;
}

The problem is that when any of the players wins the game dies. I can't find the problem and my friends couldnt find the problem either. I hope that someone here can find the solution to the problem.

I appreciate all help I can get!

What do you mean - the game dies? The game loop exits, the program prints its message and quits (perhaps closing the console window).

The only thing wrong is:

Code:

---

        row = --go/3;                             
        column = go%3;
    }while(go<0 || go>9 || board[row][column]>'9');

Because of this, user input 10 passes the first two validations but causes the blue check to access out of bounds.

Just as you said, the program closes the console window. It prints the message and quits, the players wont be able to read the last message that the program prints.

I dont want the program to close itself. It should print the last message telling who is the winner of the game and then ask them if they want to play again or quit the game.

After each scanf(), put a getchar() to pull off the remaining newline char.

Then, just before the game should end, print "Program Finished, Press Enter When Ready", message, and add one more line of "getchar().

If you want the game to loop back to a menu so it can be played again, then make it do that. That's the normal design for games.

int main


menu function
initialization depending on menu choices made
game play
after game clean up
back to top of menu function
