Neither statement is correct in Standard C++. That might be how legacy
iostreams worked. With Standard C++ iostreams: If the file does not exist,
the open fails. If the file exists, it is opened with output defaulting to
the beginning of the file. At least that's how MinGW works and it seems to
reflect what the Standard says.
