Thread: Tic tac toe, final piece...need the check winner to return values but don't know how.

So this is what the c program is doing right now... it is checking for a winner...

I need it to heck for a winner each time a move is made and since this function is called by the int main...I don't really know how I am going to do it.

could someone show me what to put in this function and then the intmain so that the game will check for a winner or draw??

Code:

int checkWinner(char cell[])
{
int i;


// Diagonals
if (cell[4]!=0 && (cell[4]==cell[0] && cell[4]==cell[8] || cell[4]==cell[2] && cell[4]==cell[6]))
return cell[4];


// Horizontals
for (i=0; i<9; i+=3)
if (cell[i]>' ' && cell[i]==cell[i+1] && cell[i]==cell[i+2])
return cell[i];


// Verticals
for (i=0; i<3; i++)
if (cell[i]>' ' && cell[i]==cell[i+3] && cell[i]==cell[i+6])
return cell[i];


// No match
return ' ';




}

my int main funt right now....(ask if you would like to see whole code..

Code:

int main()
{
    char cell[9];
    int cont = 1;
    int ccode = 0;


    info();
    init(cell);
    gameBoard(cell);
    while(cont)
    {
userMove(cell);
gameBoard(cell);




//check if user wins
//if user wins, print user won
//and cont-- to exit loop
computerMove(cell);
gameBoard(cell);


checkWinner(cell);


//check if computer wins, print computer won
//and cont-- to exit loop
//if nobody won get another user input
      }


    return 0;
}

basically the checkwinner is not doing its job right now....its just there but the game works....

so i put in the main

Code:

int winner;

winner = checkWinner(cell);
if ( winner != ' ' ) {
  printf( " you win!!!!\n", winner);
  break;

and this works perfect!

shall I do the same for the computermove??

heres what I was thinking of doing, however...when the gameboard fills up....it still says I win....:/

can someone help me fix? this is in main

Code:

int winner;

winner = checkWinner(cell);
if ( winner != ' ' ) {
  printf( " you win!!!!\n", winner);
  break;


  {
      if( winner='o')
        printf( "you lose to a machine!??????!!?!?!?!\n", winner);


        else("you lose", winner);
  }

BUT I want to stick with this one...

it will be too much work to even start a new way which I've no clue on executing yet......:\

get it to display only if it actually is a draw

Code:

winner = checkWinner(cell);
if ( winner != ' ' ) {
  printf( " you totally won!!!!\n", winner);
  break;


  {
      if( winner='o' )
        printf( "you lost!?!!?!?!?!\n", winner);




  }
  }else{
      printf("DRAW\n", winner);


  }
}
