I know this is a recurring discussion (I've spent the last 3 days
reading through threads on the topic), but I feel compelled to start
it up again.
After reading through the existing threads, I find myself convinced
that exceptions are a better mechanism, for example because
constructors and operators can't return errors, and code that...

"Load" and "Load2" are bound to "Include" while "Main" accesses variable
from "Include". I can only modify one source code before C++ compiler can
be able to compile one source code at this time so it does not need to
recompile all unmodified source codes. If I add or modify one header code,
it causes C++ Compiler to recompile all unmodified...

Hi,
One of the disadvantages of using error handling with error codes
instead of exception handling is that error codes retuned from a
function can be forgotten to check thus leading to
unexpected run-time problems. Exceptions on the other hand can not be
simply ignored.
In order to solve this error codes problem I suggest using error...

Hi,
There is code in Alison Balter's excellant "Mastering Access 2003" to
create a list of error codes and descriptions but it only generates
error messages 3 through 94. Is there a website with a list of all of
the error messages (with descriptions?).
Thanks,

{
int i = 2;
}
int i = 1;
There is no 'i' defined in the 'parent' context from the moment of
declaration on. So what is the problem? They tell us they pursue language
simplicity. The rule "do not define a variable more than once in the same
context" is natural, and simplest therefore. All normal languages obey it
therefore....

Hi.
(crossposted because the program is in C++ and some C++-related
elements are discussed, hence comp.lang.c++, plus general program
design questions are asked, hence comp.programming.)
I'm making this bignum package in C++. I'm wondering though on how to
handle the errors. Right now most operations routines return error
codes if they...

Hi,
I would like to have someone comments on what's the best practice
defining error codes in C.
Here's what I think:
solution A:
using enum
pros: type safe. better for debug (some debugger will show the name
not only the value)
cons: enum can not be forward declared which makes all error codes

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. ...

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.
