'std::cout << std::endl' is equivalent to 'std::cout << '\n' << 
std::flush', so you're flushing three times here.  That's a bad idea 
because flushing slows down the program.  I recommend this:

   std::cout << horizontal << "\t" << vertical << "\t\n" << std::flush;

Flush exactly once, at the very end of your output, and always use 
'std::flush' instead of 'std::endl' because 'std::flush is more explicit 
about your intention.
