Answer: 34
confirm the answer with http://codepad.org/PudiZIaS
Explanation:
by order of precedence, parenthesis hav highest priority
so
(i=1)*i-- - --i*(i=-3)*i++ + ++i
i=1 i=-3
now, i=-3
after assignment operations the expr becomes,
>(i)*i-- - --i*(i)*i++ + ++i
next higher priority is for auto-in/decrement
omitting post in/decrement(as they hav effect only after
this line of code), we get,
> i*i - --i*i*i + ++i
the associativity for printf statement is from right to left
so ++i is executed first before --i where i=-3
> i*i - --i*i*i + -2
now i=-2
> i*i - -3*i*i + -2
now i =-3
next precedence is for multiplication
> -3*-3

-3*-3*-3

> 9 - -27 + -2
> 9 + 27 -2
> 9 + 25
> 34
