Hello all,
I have recently been porting code from Linux to cygwin and came across
a problem with static const class members (discussed below). I am
seeking to determine whether I am programming non-standard C++ or if the
problem lies elsewhere.
To summarize static const class members are not being accessed properly
when accessed from a...

Any opinions or comments on the following? I don't say it below, but I came
out on the side of using enumerations over static constants.
/* I'm trying to figure out the pros and cons of using static const

Sorry about the big code dump. I tried to get it down to the minimum
required to demonstrate the problem. Although this is all done with GNU, I
believe the problem I'm having may be more general. Someone on the SuSE
programming mailing list suggested my problem is that I'm trying to execute
a function (I assume he meant the constructor) at...

"Defining static const variables inside the class is not universally
supported yet, so for now I guess you'll
have to move the definition out of the body of the class.
No, static const inside classes is only allowed for integral consts, like
static const enum and static const int, not for arrays and structs. It does
make sense for an array...

const static int ARRAY_SIZE = 4;
Comeau online gives this warning:
"ComeauTest.c", line 10: warning: storage class is not first const static
int ARRAY_SIZE = 4;
Why is static const preferable to const static?

hi folks,
i have a bunch of strings used in my code in many places.
these strings reside inside a instantiable class.
so, i want to replace these with constant/static variable to control
the occurences.
i have been looking at both static and const variables as the options,
but couldn't decide on one.

Hi,
In a header file I tried const char *someval="this is a test"; which
is included all over the place and I get linker errors about multiple
defines.
Why is this not folded when const char someval="this is a test"; is
and I get no linker errors?

Hello,
I would like to know whethere there is a difference between
a const variable and a static const variable inside a class.
After all, if a variable is const in a class, the compiler can
always optimize and turn it into a static const variable to
save runtim memory/stack space since being const it
cannot be changed. (?)
Thanks,

Hello everyone,
I have a Packet class I use to send packets over the Internet. All the
packets sent in a session are supposed to share a common random ID.
I figured I'd use a static const member inside my class.
class Packet
{
static const int session_id;

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not.
