Problem with output

I recently wrote this program that displays (command-line program) a tic-tac-toe format to be played. I had started the program and wrote the function to print out the board with the specified occupied spots (an array). I tested it out, and I got a weird printout with numbers instead of the ' ' char or the 'O' char. Can you please take a look and tell me what's wrong?:

Code:

---

/****************************************************
        TicTacToe -- a program to simulate the game *
****************************************************/

#include <stdio.h>

/***Function Prototypes***/
void printbrd(int pieces[3][3]);

int main()
{
        int pieces[3][3] = {{0,0,0}, {0,0,0}, {0,0,0}};

        /**print out the board for first time viewing**/
        printbrd(pieces);

        return 0;
}

void printbrd(int pieces[3][3])
{
        char lines[3][20] = {"( ) ( ) ( )", "( ) ( ) ( )", "( ) ( ) ( )"};
        char space[3][3];
        int i, j;

        for (i = 0; i < 3; i++) {
                for (j = 0; j < 3; j++) {
                        if (pieces[i][j] == 1)
                                space[i][j] = 'O';
                        else if (pieces[i][j] == 0)
                                space[i][j] = ' ';
                }
                j = -3;
                sprintf(lines[i], "(%c) (%c) (%c)", &space[i][j], &space[i][j+1], &space[j+2]);
        }

        /**print out the lines that are pre-configured to the right**/
        printf("%s\n", lines[0]);
        printf("%s\n", lines[1]);
        printf("%s\n", lines[2]);
}

Thanks!

try this:

sprintf(lines[i], "(%c) (%c) (%c)", space[i][j], space[i][j+1], space[i][j+2]);

Nope. Still doesn't work. Anything else that is wrong? Thanks for the reply!

Hi!

sprintf(lines[i], "(%c) (%c) (%c)", space[i][0], space[i][1], space[i][2]);

this should work...

Nope, still doesn't work. The same distored output. But, thanks for the reply. I can't figure it out. It is probably something with my multidimensional array's definitons/implementations. Thanks, though!

I was quite convinced that that was the problem...
This code works flawlessly here:

Code:

---

#include <stdio.h>

/***Function Prototypes***/
void printbrd(int pieces[3][3]);

int main()
{
  int pieces[3][3] = {{1,0,0}, {0,0,1}, {0,1,0}};

  /**print out the board for first timeviewing**/
  printbrd(pieces);

  return 0;
}

void printbrd(int pieces[3][3])
{
  char lines[3][20] = {"( ) ( ) ( )", "( ) ( ) ( )", "( ) ( ) ( )"};
  char space[3][3];
  int i, j;

  for (i = 0; i < 3; i++) {
      for (j = 0; j < 3; j++) {
        if (pieces[i][j] == 1)
              space[i][j] = 'O';
        else if (pieces[i][j] == 0)
              space[i][j] = ' ';
      }
      sprintf(lines[i], "(%c) (%c) (%c)", space[i][0],
            space[i][1], space[i][2]);
  }

  /**print out the lines that are pre-configured to the right**/
  printf("%s\n", lines[0]);
  printf("%s\n", lines[1]);
  printf("%s\n", lines[2]);
}

Thanks for the code!!! Hmmm...I can't see it. What did you change from my code? I should know that for future reference so I don't make that mistake again. Thanks, again, for the code! I really appreciate it, alex.
