  cout << larger(static_cast<long>(12), static_cast<long>(13))
       << endl;

  return 0;
}

double larger(double a, double b)
{
  cout << " double version. ";
  return a>b ? a : b;
}

long& larger(long& a, long& b)
{
  cout << " long ref version. ";
  return a>b ? a : b;
}

double version. 2.5
 double version. 13
