ticTacToe program, logic help!

Hi, thanks for looking at this.

Here is what i have so far:

Code:

int printBoard(int x, int y, char array)
{
  int x;  //row
  int y;  //column
  char board[3][3]; /* declares an array for the gameboard */
  
  for ( x = 0; x < 3; x++ ) {
    for ( y = 0; y < 3; y++ )
      board[x][y] = '-'; /* Set each element to a dash */
  }
  printf( "Tic-Tac-Toe board:\n" );
  for ( x = 0; x < 3;x++ ) {
    for ( y = 0; y < 3; y++ )
    {
    printf( "%c",board[x][y] );
    }
   
  }
  
}

So this basically prints a 3 x 3 matrix with '-' in each position. One question is how can i return the output to my main function? can i say

Code:

return printf( "%c",board[x][y] );

I also need help understanding how to use a function like this and some how incorporating this function:

Code:

 int userMove() {
  a = scanf("%d%d");
    i = a / 10;
    j = a%10;
    board[i][j] = 'x';    //user is an X
}

So this just assigns an 'x' to a user specified location in the 3x3 matrix. I can't get my mind around how to save this into the printBoard function. It continues to print out a 3x3 matrix full of dashes but when the user inputs the first 'X' how do i tell the function to exclude that certain position and instead print the 'x'. Any help understanding this would be great.

Either declare your board array globally or in a function that calls other functions.

So for example:

Code:

int main(void)
{
    char board[3][3];
    ....
    printBoard(board);
    ....
}

Incidentally, your printBoard() function has some weird things. You have x and y passed to the function, but then redeclared, which is rather silly. You also pass a char to the function but you call it array. Also, returning the result of printf() is not what you want.
