Thread: New Tic Tac Toe program. Only need help with int main function...

can you please explain the return int a little more???? thanks

Code:

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


void info()
{
    printf("TIC-TAC-TOE\nWritten by MEEEE\n");
    printf("Your Symbol 'x'");
    printf("Computer Symbol 'o'");
}


/*initialize board*/
void init(char cell[])
{
    int i;
    for (i=0; i<9; i++)
        cell[i] = ' ';
}


/*print gameboard */
void gameBoard(char cell[])
{
    printf("\n %c | %c | %c \n", cell[0], cell[1], cell[2]);
    printf("---|---|---\n");
    printf(" %c | %c | %c \n", cell[3], cell[4], cell[5]);
    printf("---|---|---\n");
    printf(" %c | %c | %c \n\n", cell[6], cell[7], cell[8]);
}


/*player moves*/
void userMove(char cell[])
{
    int i = 0;
    int cont = 1;


    do{
        printf("Your Move (0-8): ");
        scanf("%d", &i);


        if((cell[i] != ' ') || (i < 0 || i > 8))
        {
            printf("Invalid Input\n");    //invalid input
        }
        else
        {
            cell[i] = 'x';
            cont--;        //set while loop to false, break
        }
    }
    while(cont);
}




/*computer moves*/
void computerMove(char cell[])
{
    int i = 0;
    int cont = 1;


    do
    {
        if(cell[i] == ' ')
        {
            cell[i] = 'o';
            cont--;
        }
        else
        {
            i++;
        }


    }while(cont);


}


char 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 ' ';
}






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;
}

i was actually talking to the other guy since he's actually more helpful.

Could you guide me into how to get the checkWinner to actually do its job during the game? It is not working as of now....

Code:

int checkWinner(cell)
{
//Do all your checks
//if you found out someone won,
//check if that cell is an 'x' or an 'o'
//if it's an 'x' return 1
//if it's an 'o' return 2
//if no one won, return 0;
 }

Then in your main if return is 1, print user wins, if return is 2, computer wins, if return is 0 get another move.

do you think you could just give that one to me pleaaaase....it's so late I don't really know anymore.......
