#1. Not if you fopen in binary mode with an ANSI compiler.
#2. Don't ever use scanf!!!

This is not true. They must behave as if getc and putc were used,
and the macros may well be much faster.
There may be

Again, don't fopen in text mode. But make sure that when you get a
character you put it in an int, not a char, because otherwise
EOF (typically -1) will compare equal to one of the binary char's.

Ah, some correct advice. (Also makes debugging incredibly easier,
take my word for it!)
