OK, but... what is a "binary" file?
One containing data encoded in base-2.
Or one of a system of two files that orbits around a common

cathedral, they're binary files.

they're what come out of proton packs...just don't cross them.
It would be bad.

Hello everybody,
I need to read a text file byte after byte.
Eache byte is sent to a function that scramble it
and I need to write the result to binary file.
I've got some questions -
1) How do I read the file byte by byte
2) Should I use streams? If so and I get my entire scrambled text in
stream
