His badly written rants on personalities and programming also
occasionally touch on his limited knowledge of personalities and
programming.

Mr Nilges is the clc juvenile posting pet. He has spent most of the last
year reminding readers of the errata in Herb Schildt's books. His
badly written but entertaining rants on personalities and programing
occaisionally touch on his limited knowledge of C.

Yeah. Somehow I had the errant notion that standard C had only difftime
() to offer. I'll see if I can find that other thread and read more.
Well it's not too hard to get on the scoreboard here:
dan@dan-desktop:~/source$ cat time1.c
int main(void)
{
time_t now;
now = time(NULL);
printf ("The current date and time is: %s\n", ctime(&now));

How would you know? In fact, Malcolm's comparison function was badly
broken, but you don't know enough about the language to know that.
It's not a pathological case and that isn't how C handles it, but
you're right that it was Malcolm who presented the (broken) example,

Fortran allowed fltpt DO-var until F95 officially; of course much
earlier it was widely agreed to be a bad idea, due to the inherent
'fuzz' and machine-dependence of fltpt, and little used.
F66 didn't allow from/to/by expressions; F77 (and later) does, and as

Not standardly. In C89 it *may* work; the element type must be
complete (i.e. not itself array-of-unspecified), but it is not clear
if that is enforced before or after the 'adjustment' of an array
parameter to pointer (and pointer to array-of-unspecified is OK).

I doubt it. According to dmr's HOPL2 paper, on his website as
chist.html, B like BCPL had *both* semantics in & and | -- in a
predicate context they shortcircuited, and in a value context they
fully evaluated. He added && and || precisely to split off the
shortcircuit semantics, leaving & and | (and ^) bitwise.

I take issue with this childish use of language: "what the programmer
'wants'. What the user 'wants'". In applications programming,
correctness and maintainability are what's needed, not satisfaction of
desires.
The "credit crisis" alone reveals that what many "rocket science" C
programmers in finance "wanted" was to make their boss happy by

Malcolm of course made no mistake, since he was presenting example
code in a discussion of how C handles a pathological case. However, it
seems that entirely too many posters here are recovering from
dysfunctional and lower middle class family systems in which a father,

OK, some compilers generate a warning. In many cases those warnings
can be turned off. Whereas in Java and in .Net the status of a
noncompliant program is a single data point which is known after each
compile. You can still run the code, but both Java and .Net speak
"with one voice" about your code. It's "unmanaged" in .Net and this

Do your homework instead of reading one or two posts. Heathfield is
not a C authority nor an authority on programming. Instead, he's some
sort of manager who enables and spreads lies and gossip about
competent people which through repetition become the "truth" for the
Real Knuckleheads.
