hi all,
i found it interesting that cat.c compiles after removing these
includes:
#include <ctype.h>
#include <err.h>
#include <errno.h>
#include <string.h>
#include <unistd.h>
im just curious to hear opinions and learn something ;)
That's probably because all these files are implicitly included by
some other include files. However, it is more correct to keep them all
here explicitly because cat.c uses them directly; you should want
someone reading the code to have a list of 'libraries' it relies on.
Good question.
