very good site, thanks very much
The "code" at that site is full of errors, typos and undefined
behaviour. You would do well to eschew it and instead go here:
<http://www.c-faq.com/>
<http://www.clc-wiki.net/>
Also note that for general C discussions use the comp.lang.c group. This
group (comp.std.c) is only for discussing the details of C's standards.
Agreed. The solutions are also largely incorrect or incomplete.
If I were looking for a competent programmer I would not want the one
who wrote these.
