Is cin a suitable file?

Question

Like in, can I pass cinany function that takes an ifstream object?

Answer 1

std::cin- This is not a file stream, but an input stream, or istream. You can pass it to any function that accepts istream.

Answer 2

std::cinis std::istream.

There are few differences between a class istreamand its derivative ifstream. ifstreamallows you to open and close files, providing open(), close()and is_open(), and a constructor that calls open()- and what it is!

, istream& ifstream&.
