Hi all,
I have been asked if the following is possible.
i googled for it,thought a lot about it and decided that it is
not possible,but i am posting it here in a hope of getting this
problem solved.
---------------------
if(x)
{
printf("Hello");
}
else
{
printf("world");
}Is there any value of x for which output would be Hello world?
-------------------------
Thanking you all in advance

Yes.
#define x printf("Hello ") == 42

No.
OTH, if somewhere you don't terminate output with '\n' or flush it, you
may see nothing at all.
If x can be anything ??
Give a printf statement which prints "hello" in the place of x.
And negate the whole thing. Put it as --> if ( !x ).
The printf will return 5 and the negation will make the condition fail
and the printf in the else part will work. It will print "hello world".

Perhaps you don't understand if/else...
it's just either .. or and not both :-)

#include <stdio.h>
#define x (printf("Hello "),fflush(stdout),0)
int main(void)
{
printf("[output:]\n");
if (x)
printf("Hello");
else
printf("world");
putchar('\n');
return 0;
}
[output:]
Hello world

Here's one:
#include <stdio.h>
int y = 1;
#define x (y-- ? main() : 1)
int main(void)
{
if (x)
printf("Hello\n");
else
printf("World\n");
return 0;
}

A nice devious mind at work :-)
