i find this question from mock exam.
what is the output displayed by the following programe?
[CODE]
class Question{
public static void main(String args[]){
int n = 7;
n <<= 3;<br /> n = n & n+1 | n+2 ^ n+3 ;<br /> n >>= 2;
System.out.println(n);
}
}
can any one suggest fast way to calculate 'n' value.
I think this type of questions will take more time in exame. Is it possible to get this type questions in real exame.
Regards
Satish

Hi Satishind,
First, I can't believe we will have a so complex question at the exam (I'm attending it on Thursday) because operators precedence are difficult to memorise properly. It is always advised to use parentheses to make a code more explicit to the reader.
Anyway, the easiest way to work out the results of binary operations is to express the result in binary form.

Please tell me if this is still unclear.
Regards,
Beno�t
