What value can be given to x such that the output is "Hello

I think you misrepresented the trick question.

With `x` an `int` it will never work.

[... snip code with rewritten main() ...]

I don't think you were allowed to change the `if` statement. Have a
look at my other post as well.

Show me where this constraint was mentioned

The original post said:

All you're allowed to do is give x a value.

If you're allowed to modify the code, why not just:

#include <stdio.h>
int main(void)
{
printf("Hello World\n");
}

No, it wouldn't - I didn't wish to allude to tHGttG. Instead I alluded
to something else.

You got me there. I dont get the allusion.

[17 *is*, more often than not, my staple "random" value, but I doubt
you know me that well. ;-)]

But everyone knows that 17 is the "least random" number. Use 37 instead.

S'not portable - there's no final newline after the World.

int x = (printf( "Hello, World\n" ), exit( 0 ), 17);

will do fine.

Yep. Using 42 instead of 17 would have been even better. ;-)

Well, occasionally I use 57 instead.

(Probably has something to do with how it sounds in my native language.
Interestingly, although I fully think in English when I use it, I
still always think numbers in my native language. I don't understand
it, really.)

Results 1 - 10 of about 76 for "57 card carrying communists".

Results 1 - 10 of about 176,000 for "57 varieties".

There was of course a clue in my signature. Don't worry - the allusion is
obscure; I just wanted a change.
