I see expected behaviour here if you use a buffer of length 4. I 
don't know what you want to achieve here. If you want to stop 
reading from stdin, you should check for eof() instead. You 
should not check yourself for the character. eof() can be lock in 
by multiple ways and it is the only correct way to handle all of 
them.
