How come C allow structure members to be addressed like an array ?

[pereges]

#include <stdio.h>

typedef struct
{
double x, y, z;
}vector;

int main(void)
{
int i;
vector v;
double *cord;

v.x = 10;
v.y = 1;
v.z = 2;

cord = &v.x;

for(i = 0; i < 3; i++)
{
printf("%f\n", cord[i]);
}
return 0;
}

here's the output i get:
10.000000
1.000000
2.000000

which is the same as v

i don't how it happens as i was just trying some random ideas but
great stuff really. helped me to reduce some of my code to almost
1/3rd its size.

The fact that you've misread it might be taken as a clue.

True. I only now realized the additional n

Probably he cares more about making a nationalist point than making
life simpler for people using non-unicode aware
terminals/newsreaders. It's interesting that most Russian, Chinese
and Japanese posters are able to swallow their pride enough to
Latinize their names.

Well, that helps me get a clearer picture of how you see the world.

I think it is quite reasonable that people should be able to spell
their names correctly, but that argument will be lost on someone who
does not even dare let their name be know.

You appear to have totally missed the point. If you re-read Twinks
reply then all the necessary points are therein.

Hint : Most usenet posting Germans convert the German characters to
"oe", "ae" and "ss" etc as appropriate.

In Postings yes, but not neccessarily in Names

Yes, I got that - I was just commenting on Thomas's seeming confustion
on how floating-point numbers behave.

I passed no judgment, but merely tried to explain Thomas's likely
thinking.

Thomas can and should do what he likes. I very rarely read Usenet other
than in a Unicode-aware environment, but when I do it's a pain to have
the terminal screwed up by Thomas or Harold van Dijk's non-ASCII
characters. People with strange characters in their name need to decide
whether it's more important to use the "right" spelling of their name,
or to maximize the number of people who can read their messages without
a problem. I pointed out that Thomas makes a decision that's different
from many other people - I neither endorse nor condemn him for that.

And you mis-transcribe/-spell them, there's no h in Tomás and no o in
Harald. And nothing in these characters is funny.

Accurate observation, even for a trolling thick.

It's
interesting that most Russian, Chinese and Japanese posters are able to
swallow their pride enough to Latinize their names.

I've always hastened to use the cliché term "There's nothing worse
than X", but in this case they're the only words that come to me:
There's nothing worse than a people without pride. There's plenty of
immigrants in the town where I live. There's Eastern Europeans.
There's black Africans. While I'm not overjoyed with immigrants taking
natives' jobs and accommodation, I don't bear any real animosity or
hatred towards them. Some of them are really nice people, and they're
just here to make a better life for themselves. In fact, their
ambition in life is something a lot of people could aspire to. The
black Africans in particular tend to be extremely pleasant friendly
people; I can smile and say hello to a complete stranger black
African, and he'll say hello back with a warm smile. If I were to do
that to any other stranger, the person would look at me like I'm a
weirdo.

But then there's one immigrant people here that I truly despise: Roma
gypsies. These people have no pride whatsoever. They really are rats.
They come into my country illegally and create encapments at motorway
junctions. They teach their children how to walk in a way that makes
their bare leg look mangled, and then they send their kids to beg
between cars on the road at a busy motorway junction. They have a
mouth full of gold teeth (yes, actual gold, the rare chemical
element), and they drive BMW cars (for those who don't know, BMW is a
luxury car make), but yet they send their children to beg on the
roads. They don't wash their bodies.

Lastnight I was in a shop in my hometime where a friend of mine works.
A Roma gypsie man came up to the counter and asked if anyone could
read a German letter for him. I like to give people the benefit of the
doubt and to be open to friendship with new people, but in this case
this was very naive of me. I read the letter aloud for him. Next, as I
was leaving, he came over to me and snooped around at my car asking me
how much I'd sell it to him for. Again, being naive I plainly told him
"No sorry, I need this car to get to work, it's not for sale" while he
snooped around the car looking in my driver's door.

When I got home, I noticed something was missing. Something which I
had when I was reading the letter for him, but which was gone by the
time I got into my car.

Now up until that point, I'd never been a fan of Roma gypsies, but at
the same time I'd no real animosity or hatred for them. Now though, I
don't even see them as people. There are friends of mine who work in
shops that have had far more experience with Roma gypsies than I have,
but I've never really understood the venomous hatred my friends have
had for them. But now, I understand.

But I digress, there's nothing worse than a people without pride. I'm
Irish, and I'm from Ireland. The vast majority of people in my country
have English names, you'll see "Stephen McAteer" instead of "Stiofán
Mac an tSaoir". Now if they feel comfortable with that, then that's
fine. But personally I don't feel comfortable as an Irish person with
an English name. I'm Irish, I speak Irish and I've an Irish name.
Suits me much better.

><snipped: anecdote of alleged theft by Roma gypsy>

I've just been back from that shop I was in and my mate had a look
over the cameras with me. I put the object on the roof of my car as I
was talking to the gypsie, and as I turned around to unlock my door he
swiped it an put it in his coat. The camera shows it clearly.

>One Roma gypsy (allegedly) steals from you, and now you say that, as a result
of this, you don't even see them as people.

Not allegedly, definitely. Witnessing their thievery first-hand was
the straw that broke the camel's back. Up until then I was well aware
of their reputation as being a dirty filthy race of people, but the
idea hadn't been cemented in my mind as I hadn't witnessed it first-
hand.

>Quite a few Irish people have been responsible for the indiscriminate killing
of a great many people since the 1960s. By *your* logic, we should despise
the Irish and not see /them/ as people. We should accord them no rights, and
give them no quarter.

If I'd been robbed by a German I would _not_ have tarred them all with
the same brush. Same goes for an American. Or a Japanese person.

Roma gypsies are a different animal altogether.

Hitler would have agreed with you.

Yes, it's amazing how conversations quickly turn sour when someone
introduces a racist tirade into them.
