Het is niet nodig om het bord char per char te teken. Bv:

      String stars(k,'*'), spaces(k,' ');
      String odd_line(""), even_line("");
      String odd(""), even("");

      for (int i = 0; i < n-1; ++i)  // loop over columns
          odd_line += ( (i%2) == 0 ? stars : spaces );

      even_line = spaces + odd_line;
      odd_line += ( (n%2) == 0 ? spaces : stars );

      for (int i = 0; i < k; ++i) {  // group 'k' lines together
          even += even_line + endl;
          odd += odd_line + endl;
      }

      for (int i = 0; i < n; ++i)  // loop over rows
          cout << ( ((i+n)%2) == 0 ? odd : even );

En verdere 'optimalisaties' zijn natuurlijk ook mogelijk. Bv de laatste
loop over 'int i=n; i<2*n; ++i' laten lopen en dan testen op i%2 ipv
(i+n)%2.
