Unknown cin properties

Question

Try as I might, I cannot find any information on what cin.binary is for.

similar ones, thinking bases, dec, hex, octal only seem to appear when used with cout - e.g.,

cout << std::hex << n;.

However cout << std::binary << n; isn't valid

Entering cin. produces this intellisense popup

I'm left assuming that these are some sort of flags. Sure would be nice to know for sure though.

Did you try [looking at the documentation](http://en.cppreference.com/w/cpp/io/ios_base/openmode)? — Algirdas Preidžius, Jan 18 '17 at 16:19
you could have saved some typing if you simply searched those on web — P0W, Jan 18 '17 at 16:22
Of course I did try looking on the web. "cin.binary" doesn't give any result that actually include that exact string. — peedurrr, Jan 18 '17 at 16:37

binary is a flag to tell the stream to be opened in binary mode (instead of textual mode).

You might also search on this site for other flags and functions of std::basic_istream(e.g. std::cin): http://en.cppreference.com/w/cpp/io/basic_istream

binary is used to open a istream in binary mode (as opposed to text mode).

std::cin is not open in binary mode, please read the answers here for more details.
