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

Wrong. main returns int.

There is no 'textcolor' function in standard C.

textbackground( 123); /* use this inbuilt function to change the color

There is no 'textbackground ' function in standard C.

This is entirely system-specific.

What do you want the line to be drawn on ? Be very specific.

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

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

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

So what?

be helpful or don't get involved.

_Some_ M$ platforms.

textcolor(8); // Use this inbuilt function in C to change the color
of text

There is no 'textcolor' function in standard C.

Or perhaps Mr. georgerzx should not be using terms like "inbuilt
function in C".

Et too... No need to keep up the "this is not standard C" mantra Either

Pointing out that code given out may well not work on the OP's platform
is very helpful.

Nothing in the rules says that <conio.hcan't be used for any purpose
on any platform. It's perfectly legal to release a library on a
Microsoft platform (or on any other platform) that publishes its
interface via a header named <conio.h>, no matter what functionality
that library provides, graphical or otherwise.

>>void main()

Wrong. main returns int.

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.

>>{

you should not be giving any advice.

I agree that it is likely that he's using Turbo C under MS-DOS or
MS-Windows, but the C Standard does not guarantee this.

The C standard is not relevant at this point. What is relevant that he
constructs a good program using C with the extensions available for his
platform. Portability is a non issue here.

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

Are hosted implementations free to accept void main(void) if they wish?
Obviously they must still accept int main(void).

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.

however if he is using conio I think it is
fairly safe to assume he is on an MS platform so it should return an
Int

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

The C standard is not relevant at this point.

If that is the case, then he would be better off seeking advice in a
newsgroup dedicated to discussing his implementation.

Very true. Nevertheless, whether it *may* (i.e. is allowed to) return
something other than int (and still remain a correct program) depends
on the criteria I gave.

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

Yes. Implementations , hosted or otherwise, have always been free to
provide extensions which do not break correct programs. Furthermore,
they have always been free to accept incorrect programs.

Obviously they must still accept int main(void).

Indeed.
