public static void Star1(int n)

      int k = n;
      int temp = n;
      Console.WriteLine();
      while (n > 0)

        Console.WriteLine();
        n = n - 1;
        if (n > temp / 2)
        {
          k = k - 2;
        }
        else
        {
          k = k + 2;
        }

      }
    }

This program will work for odd values of n
