Hello All!
I'am novice in python, and I find one very bad thing (from my point of view) in
language. There is no keyword or syntax to declare variable, like 'var' in
Pascal, or special syntax in C. It can cause very ugly errors,like this:
epsilon=0
S=0
while epsilon<10:
S=S+epsilon

Perhaps one of the experts can straighten me out on this point...
In Bjarne Stroustrup's book 'The C++ Programming Language' 3rd Edition,
section 4.9, indicates that
typedef complex<short> Point;
is not only a declaration, but also a definition.
The ISO/IEC 14882:2003(E) standard states in section 3.1 clause 2 that

My question is about the use and meaning of the terms "declaration" and
"definition" as it pertains to the C language.
I've read sources that mix the two up when talking about such things as
setting aside storage for an object, defining/declaring a struct, parts
of a function, referencing an external variable in another module.

extern long globalfoo; /* declaration? */

Hello,
I was told that if I declare a static class constant like this:
class A{
static const int x = 10;
};
then the above statement is a declaration rather than a definition.
As I've *defined* "x"'s value to be 10, isn't above statement a

Does a template class declaration, like
template <class T>
have to come immediately prior to the declaration of the function,
e.g.,
T do_something (T something)
{ . . . }
that uses it?

I find friend declaration just very tricky. I tried the following
examples on both MingW(gcc 3.4.2) and VC++ 2005. The results are
surprising.
Example1:
namespace ns1
{
class Test
{
friend void func()

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.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

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. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
