As far as I can tell, the following three things are not on the exam objectives:

1) NaN (as in comparing with a NaN etc)
2) << or >> (as in int i = 16; i >> 1 = ?)
3) ~ (as in int i = 787; ~i = ?)

But I've seen them, specially the latter two on many mock exams. Is it just a case of older questions, or can they show up on the exam?

Thanks,
Nidhi

They are probably very old mock exams. Yes they are not part of the real exam
