Any reason not to use strcpy, strcat or scanf?

["A.V." <pahalial.lists () gmail com>]

Hi,

I was simply wondering after seeing the "blackhat audit" program sent
to F-D whether there was actually any reason not to use these
functions (strcpy/strcat/scanf) in your code. I mean, I understand why
you shouldn't use scanf to i.e. process user input, but other than
that? Some kind of unexpected behaviour or something?

Thanks,
A.V.
