Did somebody change the automatic stdout.flush behavior?

Now I'm in doubt. That's ancient knowledge (belief) for me from C and 
C++ days. I swear there was a feature where you could link (or lock, or 
connect?) an output stream to an input stream and reading from the input 
stream would automatically flush the output stream.

And I've been under the impression that stdin and stdout were such 
streams. But the internet does not agree with me. Was I dreaming? Was 
that a special thing about C++'s cout and cin?

Help! Losing my mind...

P.S. Regardless, an automatic flush feature would be nice between stdin 
and stdout. But I wouldn't want that unless it "is a tty". Hm... I think 
I see now.
