about Pointer

#include <stdio.h>

int main()
{
printf("%s",*("abc" + 1));
return 0;
}

i expected this would show 'bc'

but, Compile error message : format argument is not a pointer (arg 2)

as far as i know, "abc" + 1 is pointer , right ?

Could anyone explain about this ?

TIA ^^

Herrcho...

Right; but *("abc" + 1) is not a pointer.

Yes. But *("abc" + 1) , which is the expression you
supplied for the argument, is not. Its type is 'char'.

printf("%s", "abc" + 1);

Um, you didn't look at your code carefully enough? :-)

("abc"+1) is a pointer. *("abc"+1) is a char. Try:

printf("%s", ("abc"+1));

--
main(){int j=1234;char t[]=":@abcdefghijklmnopqrstuvwxyz.\n",*i=
"iqgbgxmdbjlgdv.lksrqek.n";char *strchr(const char *,int);while(
*i){j+=strchr(t,*i++)-t;j%=sizeof t-1;putchar(t[j]);} return 0;}

Yes, but I won't. Other, more benevolent persons, have already taken the
time to point out your short comings.

If hindsight is 20-20, then you must have perfect vision, becuase your an
ass.

A few rational people have answered the question.
Yours is the only reply I see that contains an insulting
tone (and contained no useful info btw).

An obvious novice with C asked a valid topical question,
responses to which would be educational to any
other 'newbies' reading.

How does this make Herrcho an 'ass'?

You, however, look like an inconsiderate jerk who cannot
even spell simple English words.

Rational? I think you are making assumptions, or what we might refer to
as "hasty generalizations".

Again, you are wrong. My tone is one of mirth, not insult. To be
absolutely clear, I was joking! I was trying to highlight how much of a
jerk everybody else in this newgroup is.

The only accurate thing you've said so far. I am a jerk. I am
inconsiderate, and unlike you I don't use spell checkers.

No, your tone is one of obnoxious insult.

If you were joking, then I (for one) fail to get it. You blatantly
called the OP an ass. AFAICS, the only assinine person here is you,
Clod.
[color=blue]
>jerk everybody else in this newgroup is.[/color]

You highlighted yourself, Clod, only yourself. You called attention
to your own idiocy. But, like idiots everywhere, you seem unable to
see yourself for what you really are.

No, Clod, that was insulting. If you thought that was funny, then
you must be seriously disturbed. You need urgent psychiatric help.

I bet he learned that you are an idiot and a troll, and that you are
not worth wasting any more effort listening to.

Everything Mike has said so far is accurate.

You would be wise to start using one, then, Clod. I don't think Mike
uses one, though. I don't think he needs one. (I could be wrong,
though.)

And since he has plonked you, your foul-mouthed insult will fall on
deaf ears, so to speak. But everone else in this newsgroup will see
what an obnoxious dick you really are.
Go away, Clod, you troll, until you learn to conduct yourself with
proper decorum.
