that I saw...
It was as follows:

right shift is ok..But what is meaned by " i = ~0 "... 26 1998

Same as "i = -1;" I suppose.

Tilde is the one's complement operator. I would not think of that as
bulletproof code, the results might well be different on a one's complement
machine than they are on a two's complement machine. The result is
"negative zero" on a one's complement machine.

Not on a 1's complement or a signed magnitude machine.

Actually, it's the ones' complement operator, because it complements
many ones. "Two's complement", however, is correct.

I don't know if that is some of that famous British humour or what. It is
the one's complement operator, it does *not* form a proper two's complement.

Nope.
It is the one's complement operator,
No, it's the ones' complement operator. Observe the position of the
apostrophe. If you disagree, take it up with Knuth (TAOCP Vol 2,
Section 4.1).

I didn't say it did. I was referring to your correct positioning of the
apostrophe in "two's complement", later in your article.

Some of your alleged humour is on a par with your food. If I had not

I say again, there is no humour intended here. I am being perfectly
serious. I don't know what amusement *you* see in this discussion, but
I'm not seeing any at all.

I don't see how. You said "Tilde is the one's complement operator" and I
replied "No, it's the ones' complement operator". The correction seems
plain enough to me.
If you think my correction is spurious, I invite you to check the Knuth
reference I gave.

It has nothing to do with the legitimacy of what you are saying. You know,
this English language is expressive enough to actually say what you mean
instead of hiding the meaning behind a veil. I see no point whatsoever in
being so subtle on such a thing, as I said, your initial post could easily
mislead someone.
FWIW, K&R spell it my way. My work is done here. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |
