Why would one use bitwise operators? I can program in various languages in
some shape or form (C++, PHP, some scripting) and I've heard/seen bitwise
operators before, but never understood why anyone would use them - any real
world examples or ideas? Examples follow (that I am reading in my Core
JavaScript Guide 1.5).
15 & 9 yields 9 (1111...

I'll try to explain what I want to do:
I have foo.h and foo.cpp. Units that include foo.h will define an
enumeration bar:
enum bar { typeNone, typeBaz, typeQuux, ... , count };
A method defined in foo.cpp needs to return typeNone. Is using
static_cast< bar >( 0 )

The basic understanding of what bitwise operators (& ^ | >> << ) comes
fairly simple, as long as one has a fundamental understanding of bits,
bytes and binary.
Having done some Win32 programming in straight C, the Win32 API sends
windows messages to applications with various settings stored in bit
fields, in which case changing the...

I've created a quick reference comparison of C# and
VB.NET that you might find useful. I couldn't find
anything like it on the web and so I made my own.

It doesn't cover every area of the languages, just those
features most frequently used.

Suppose I have a few Keys objects:
Keys k1 = Keys.V; // V
Keys k2 = Keys.Control | Keys.V; // Ctrl+V
Keys k3 = Keys.Shift | Keys.J; // Shift+J
I need to determine which of these include the Keys.V element,
regardless of any other keys. I know it will be a bitwise comparison,
but I can't work out the correct syntax to use.

I'm writing a map generator and I'm looking for a way to keep track of the
various terrain. I had a thought of using bitboards but I can't find a way
to bitwise AND two int's together and get a bool.
How do I get the proper response from:
IF (0x01 & 0x05)
My only recourse so far is to use the full if syntax:
IF ((0x01 & 0x05) > 0)

Hi,
This isn't *specifically* an ASP.NET question, so I've also posted it in the
ADO.NET group - however, it's not too far off-topic...
Imagine a SQL Server 2005 database with a table with an int column used for
bitwise data - you know the sort of thing... 0, 1, 2, 4, 8, 16 etc

Hi,
I just wanted to share another library for doing type-safe bitwise
operations in C++:
http://bitwise-enum.googlecode.com
I found it useful, so hopefully it'll be for somebody else as well.
BRgds,
Daniel.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it. ...
