Reading from standard in using ios::binary

Question

I'm trying to read from standard input and distinguish each character from one another by its decimal value. From what I understand, a Line Feed (10) and a Carriage Return (13) will be interpreted as the same character. I want to distinguish between the two. I know if I was reading from a file I could open it using the ios::binary parameter. But what about if I am reading from standard input?

If you know your platform, you could try to reopen stdin using an ifstream (the point I can't do it in a portable way, /dev/stdin should work for -ixes), then use rdbuf to hook that into std::cin. — Kos

Also see the discussion of using std::freopen (but it looks kind of hacky). It would be nice if someone provided a canonical answer with examples for BSDs, Linux, OS X, Solaris and Windows. — jww

You can read from std::cin by using get. This method is specially designed for reading unformatted data (see doc)

I think the problem is, std::cin is opened in text mode. There may be some unwanted translations due to text mode.
