title: How do I fix a Wint Conversion warning?
body: <p>This is a fragment of a ticktacktoe game that I started. When I compile it, the Wint conversion warning pops up, saying that clear_table(board); and display_table(board); are making integers from pointer without a cast. I'm really new at C and I'm not sure how to fix this. Plus I'm not allowed to change the main function at all.</p>
  
  <pre><code>#include &lt;stdio.h&gt;
  #define SIZE 3
  
  void display_table(char board);
  void clear_table(char board);
  
  int main()
  {
      char board[SIZE][SIZE];
      int row, col;
  
      clear_table(board);
  
      display_table(board);
  
      return 0;
  }
  
  void clear_table(char board) {
      int row = 0, col = 0;
      for(row = 0; row &lt; SIZE; row++) {
          for(col = 0; col &lt; SIZE; col++) {
              board = '_';
          }
      }
  
      return;
  }
  
  void display_table(char board) {
      printf("The current state of the game is: \n");
      int row = 0, col = 0;
      for(row = 0; row &lt; SIZE; row++) {
          for(col = 0; col &lt; SIZE; col++) {
              printf("%c ", board);
          }
          printf("\n");
      }
  
      return;
  }
  </code></pre>
  
  <p>Please help?</p>
