hi friends,

is it possible to call a variable from the main function to a sub
fuction with out sending as a argument, pointer and can't declare as
global variable?

void main()
{
int a=10;
fun();
}

fun()
{
printf("%d", a);
}

condition
1. don't use pointer concept
2.don't declare as global variable
3.don't send as arguments

IS IT POSSIBLE?

please me

Why would you want to?

Anyway, it depends on what at least "as", "global", and "variable" mean.
With some legitimate interpretations, there are certainly ways around the
pointless restrictions you (or your instructor) gave.

Search the archives of this group for the answer, which is "do your
own homework"...

....and get a professor with a clue...

In some implementations, Yes.

If you want to know *How* to do it, at the very least you'll have
to google up my posting on the topic about 2 months ago, when
someone presented the same question in almost exactly the same words.

Just look up your previous thread, when you posted using the
name "Anto Frank", using your email address j.antofranklin@gmail.com

No.

What teacher and/or school keeps giving students this question? It
gets posted in nearly identical form every few weeks.

The answer is that it's not possible unless you invoke undefined
behavior whose behavior you happen to know because you know some
intimate details about the particular compiler, including being
tied to a specific version of that compiler and a particular set
of compilation options.

Why do you expect to get anything more useful than the "it cannot
be done" answer you got the last time?

> do you have the url?

And when you can't even be bothered to look up your own messages,
especially when you were posting from Google the last time (and
even this one was routed through Google before it got to me),
don't expect people to give you very much .
