copy(istreambuf_iterator<string>( myInputFileStream ), istreambuf_iterator<string>(), back_inserter(v)); copy(istream_iterator<string>( myInputFileStream ), istream_iterator<string>(), back_inserter(v));
The reason why it is faster, is that it does not do a lot of checking, and it also uses the rdbuf() member function directly, dealing with characters of type char or wchar_t.
istream_iterator<> uses operator>>().
