That's what people thought before the Internet worm struck, yes. Believe
you me: every single use of gets() is a mistake. Sooner or later, you
_will_ get bitten by it.
As for the bug involving feof(): have you read that page? The bug does
exist. Mind you, it _is_ possible to use feof() correctly. It is usually
needlessly involved, but it can be done. If you want code that is
obviously correct, though, you usually want to avoid it.

So? I can write programs that are syntactically correct, and perfect C,
but that will print insults to my boss' heredity when run. I do not
expect a C compiler to catch logic errors, only syntax errors.
