2's complement

[eeh]

Hi,

Could anyone give me sample code to calculate 2's complement of an
integer which is n (n<16) bits length?

Thanks!

Can you..
a) Read your course note?
b) Consult your lecturer or tutor?
c) Google it?
d) Offer cash?

int a = 5;
int b = ~a;

int a = 5;
int b = ~a;

That will give the 1's complement, the result of flipping
each bit. You can get the 2's complement in several ways but
the simplest is:

int b = -a;

int a = 5;
int b = ~a;

I wonder whether the op wants to find
the two's complement form of an integer?

int a = 5;
int b = ~a;

That's one's complement. Two's is one value higher.
