You cannot have anticipatory feof from the keyboard without actually
trying to read data and perhaps blocking, and in C, keyboard and file
I/O use the same mechanism. So instead, feof was designed to be after
the fact, so that when a read fails, you can check whether it was due
to EOF or some other reason.
