#9 "The & operator can be applied to"

Well technically & is also a bitwise and operator, which can be applied to rvalues.

Oh, I have just noticed that the question is a bit ambiguous. Thanks for feedback, you're right!

Select the correct object type: ______ file("Telegram", ios::in || ios::out);
1) Second operand of fstream constructor must be ios::in | ios::out, not ios::in || ios::out (one vertical bar, not two)
2) All types: fstream, ifstream, and ofstream can be answers: https://ideone.com/YmoH7h

So, technically you can use, but in action, it won't take an effect. If you use ofstream file("Telegram", ios::in || ios::out); and try in the next line to write something in this file, like, file << "Something"; std::string forFile = "Sample"; file >> forFile; The last expression won't compile, since our file is inly for writing mode, not for reading. https://ideone.com/WcAeAm. I should have added some clarifications to questions, thanks for feedback.
