Been a while since I've done this.  I think you're one shy, and the answer is 32767.

16-bit would be 1000000000000000, and flipping the bits would yield 0111111111111111, which is equal to 32767 decimal.

To support my thinking, I found the following:

"For instance, a 16-bit word can represent signed integers in the range −32 768 to + 32 767."

which I took from:

HTH.

(edit - please excuse me if I'm incorrect, and someone tell us otherwise...  been a LONG time since I'd done these, too)

What was the subject matter of the test, out of curiosity?

Ethicalhack3r,


Just out of interest, was Mark Burrell also one of the module lecturers?
I remember some sleep-inducing lectures from him

Andrew

Must have left after my days then, tbh think the whole module got me sleeping.

Wish I'd paid more attention now I'm playing with shellcode, turns out the low-level stuff is still relevant. Who'd of thought the lecturers would have a better understanding of the industry than the students?
