我们经常使用ofstream或者fstream可写文件，使用ifstream可以写文件，但需要设置文件的打开状态为ios::out。

When using a non-converting locale (the default locale is non-converting), the overrider of this function instd::basic_ofstreammay be optimized for zero-copy bulk I/O (by means of overridingstd::streambuf::xsputn). Example This function may be used to output object representations, i.e. ...
