title: cannot convert parameter 1 from 'char [3][3]' to 'char'
body: <p>I am making a TICTAC Toe game. I'am using 2D array and I'm having problem in calling and passing the array in a function call.<br>
  What's this erroe means ?</p>

  <pre><code>char mark=move(matrix,turn,yourTurn);
  </code></pre>
  
  <p>My function move is :      </p>
  
  <pre><code>int move(char matrix[3][3],int turn,int &amp;move)
  
  {
      char mark;
  
      if(turn==1)
      {
          mark='X';
      }
      else
          mark='O';
  
          switch (move)
          {
  
          case 1:
              matrix[0][0]=mark;
              return matrix[0][0];
          case 2:
              matrix[0][1]=mark;
              return matrix[0][1];
          case 3:
              matrix[0][2]=mark;
              return matrix[0][2];
          case 4:
              matrix[1][0]=mark;
              return matrix[1][0];
          case 5:
              matrix[1][1]=mark;
              return matrix[1][1];
          case 6:
              matrix[1][2]=mark;
              return matrix[1][2];
          case 7:
              matrix[2][0]=mark;
              return matrix[2][0];

              return matrix[2][2];
  
      default:
          cout&lt;&lt;"You can only mark 1 to 9 on the board";
          break;
      }

  <p>isFull() function  This function tells me is that place is already filled or not. Its not complete yet because I'm stuck.</p>
  
  <pre><code>bool isFull(char matrix[3][3])
  {
      for (int row = 0; row &lt; 3; row++)
      {
         for (int col = 0; col &lt; 3; col++)
         {
            if (matrix[row][col]=='X'||matrix[row][col]=='O')
            {
              return true;
            }
         }
      }
  return false;
  }
