I too failed to solve "A 'C' program without using any loop (if, for, while,etc...) to print numbers."

unless it is somthing like

printf("1,  2,  3,  4....\n");
printf("1,  2,  3,  4....\n");

I get the feeling you didn't look very hard. Have you considered recursion? What about goto? Neither of those are considered to be loop constructs.

I'm here to prove you wrong.

goto was the first thing that came to my mind.
recursion was the seconed thing.

But in any case we are not allowed to test with "if".
I tought about simple condition like this

 Help with Code Tags 
 C Syntax (Toggle Plain Text) 
i = ( i < 10 ) ? i+1 : i ;
i = ( i < 10 ) ? i+1 : i ;

But its like using "if".

I tought about macros. But thats using "if" and saying
"I am not using 'if'"

Confusing directions -- you can't use a loop, but an if statement is not an iteration statement (a loop construct).
