c without usin any graphics function

[shaanxxx]

if u give cordinates to programme at run time and want a line to be
drawn.. how to do this in c without usin any graphics function?
like x1,y1 and x2,y2
and lines should be drawn from the 1st co-ordinate to 2nd one

any pointer would be appreciated

Thanks

Not always but if we are assuming "conio.h" then it should

Whether main may return something other than int does *not* depend on
the availability or otherwise of a header named <conio.h>, but on
whether the implementation is a hosted C90 implementation.

A hosted C90 platform...

The C Standard doesn't define, or even use, the term "platform", so we
can't guarantee that we are using the word in the same way.

Two programmers talking to each other can. if you can't then you have
lost all links with reality.

int (C doesn't define the term "Int"). In my previous reply I pointed
out why your assumption is not necessarily correct.

I sometimes wonder if you can hear yourself or bother to see who you are
replying to. I would say a technical meeting with you would be akin to
rubbing vinegar into ones own eyeballs while sitting on a bed of glowing
coals.

And if you were one of them, you could proffer your understanding of
the term.

(Mr Heathfield should have made the first move in that game, I agree.)

Chris (no, the other one) introduced the term. I still don't know what
he means by it. I can guess, but I don't *know*. My guess is that he
means "OS", and this guess is based on the fact that he said "MS
platform", even though it does appear that the OP is probably using a
compiler written by Borland. But I'm not certain. Maybe he means
"implementation " and believes <conio.hto be a Microsoftism.

I think it's up to Chris (no, the other one) to define the meanings of
the non-standard terms he introduces into the discussion.

But given that he didn't, I believe a better move in the game "constructi ve
discussion" would have been "I'm not sure what you mean by 'platform' here;
is it just the local OS or what?", rather than the move you made.

We have enough aggro here (yes, I'm not disputing that I've contributed;
I make no claims to perfection, only about it). I'm just wondering about
adding "crush them with kindness" to the toolbag, for whatever one's
value of "them" [1] might be. We can't all be Chris Torek -- there'd
be no room in the kitchen -- but /he/ manages to be topical /and/
non-abrasive.

It is a non issue in a technical group discussing C. Heathfield is
overly pedantic and up himself, great C programmer though he might be.

Does it matter. It works for him.

What do you mean by "discussion " here?

See? Silly isn't it.

Rounding an angle to the nearest 45 degrees, at best, wouldn't satisfy
that
by any stretch of the imagination.

The OP did not require that the drawn line proceed straight from
the beginning to ending coordinates. If the coordinates are
integral and finite, then you could draw a 45 degree line of length
min(abs(x1-x0),abs(y1-y0)), and a straight line of length
max(abs(x1-x0),abs(y1-y0))-min(abs(x1-x0),abs(y1-y0))
provided that the shorter of these two fit whatever page-size is in use.

My preference when answering is to start out by assuming the OP is not a
moron.

The word "guess" indicates otherwise. Furthermore, the person who can
say yay or nay -- viz, Chris Hills -- hasn't spoken on it yet. Your
guess is just that -- another guess.

What do you mean by "discussion " here?

Good question. "Aggravated argument" would sometimes be closer. But
while what "platform" meant seems to make a different to what Mr
Heathfield would have said, would what "discussion " means make a
difference to what /you/ say?

See? Silly isn't it.

Can't tell. By the same logic as I applied before, /your/ move should
have been to say that you weren't sure what "discussion " meant, this
is what you thought, and how did that fit?

Perhaps. I make no claim to perfection. But I wasn't trying to pull
Chris(no, the other one)'s nose or anything. I just didn't word it very
well. I still think it would be better for Chris (no, the other one) to
clarify what he's talking about.

Yes, he manages it admirably. His killfile must be simply colossal.

If we exceed the capacity of the kitchen, it follows that the behaviour
will be undefined. This is a suitable place for an implementation to
have an extension. However, I think the current kitchen (and coffee)
owner should have a say.

I don't think it's (just) his killfile.
