Okay.
Condition: Only by using below operators, We should not use any loops
or if or switch or any thing
Legal ops: ! ~ & ^ | + << >>
Ex: if (number < 0) // But, v should not use "if"
condition.
return 0;
return 1;
Waiting for clue.

Sounds like a homework problem.
This is actually moderately hard to do portably; if you're allowed to assume
that you know the target architecture, you may be able to do it by something
as trivial as masking out a sign bit. (But be wary; there probably exists
a machine where there's a -0 integer value, which would trip you up.)
