Perfectly true. In case 1, a fflush() call is made for every character
written, in 2, after every \n or once the buffer is full, and in 3,
once the buffer is full.
They are by default used in:
unbuffered - for stderr,
line buffered - for stdout to terminals,
and full buffering - for output to files.
