Thread: finding the one's complement of a binary number?

i have an array of 1s and 0s to represent a binary number. i would like to be able to manipulate the array (or maybe create a new one if neccesary?) which will represent the one's complement of the binary number.

can anybody help me with this?

What's wrong with ! ?

the NOT operator? I don't follow..lol

Well, what do you think the ones' complement of a binary number is, then?

Is the one's complement of a binary number just the bits flipped ? i.e 1 becomes 0 and 0 becomes 1?

Yes.

I thought it was the '~' operator.

Yep "~" is the one's complement while "!" is for logical negation.

That would work, except for the "array of 1's and 0's" part.
