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

#include<stdi o.h>
#include<coni o.h>

This header is non-standard.

A more useful comment is that this only works on and MS platform?

It would certainly be more inaccurate.

Wrong. main returns int.

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

Wrong again.
[markg@cpa-re-test ~]1007$ cat t.c
void main()
{
}
[markg@cpa-re-test ~]1008$ gcc t.c
t.c: In function `main':

There is no 'textcolor' function in standard C.

He is apparently using an MS platform. If you can't tell that perhaps
you should not be giving any advice.

Ah, but the OP may well not be, so Keith is correct to report the problems.

>> for(b=176;b<224 ;b++)
{
printf("\n\t %c",b);
}

/* Above for loop will print the characters available in C for
graphics programming
you can use these characters to design GUI (graphical user interface)
for your application.
Even The turboc Editor can be designed with the above characters. Just
you have to use the for
and while loop properly */

This is entirely system-specific.

So what?

So there is a good chance of it NOT working on the OPs platform and the
OP needs to know the advice given by this respondent is not generally
applicable.

How many times do you intend to advertise this site? Once was more
than enough.

Et too... No need to keep up the "this is not standard C" mantra Either
be helpful or don't get involved.

Your reply was not helpful, so perhaps you should follow your own advice.

I have consulted my trusty Chambers dictionary, which has an
approximately 200-word entry for "platform", with at least a couple of
dozen definitions, none of which can reasonably be interpreted as
having anything to do with the subject under discussion (except,
perhaps, the definition "a medium for discussion"(!), which doesn't get
us very far).

I won't attempt a rigorous definition of the term, but I've frequently
seen "platform" used to refer to the system hardware and software
supporting a given implementation of C. Surely at least one of those
dictionary entries is consistent with that usage? If not, it needs to
be updated. I went to www.ask.com and typed "what is a computer
platform" (it is clear that we were talking about "platform" in the
context of computers, right?), and recieved links to dozens of sites,
most of which confirmed that meaning.
That meaning fits very nicely the context in which Chris used the
term. I'm surprised that you're unfamiliar with this usage, and I'm
surprised that you gave any significant amount of thought to
considering the possibility that any other possible meaning applied.

Well, obviously he can't be referring to the hardware-only definition,
not if he's qualifying it with MS.

The world is larger than you realise.

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.

Even on a freestanding implementation main may be required to return int.

Are hosted implementations free to accept void main(void) if they wish?

A hosted implementation is free to accept struct tm main(ptrdiff_t
bloogle), if it wishes to. That does not mean that one should use struct
tm main(ptrdiff_t bloogle), or even void main(), in C code posted to
this newsgroup, or anywhere else where one doesn't want to be tied to a
single implementation.
