Hello,
I'm confused by the use of the Scope resolution operator on the
indicated lines in the following code (which was copied from Thinking in
C++ by Bruce Eckel). Removing them seems to have no effect.
//Begin Code
#include <new> // Size_t definition
#include <fstream>
using namespace std;

Hello :)
I am familiar with using scope resolution operator to define classes, but
why does it turn up elsewhere?
thanks

I'm learning Javascript. I downloaded a script for study. Please tell
me how the variable "loop" can have scope in the first function when
it is altered in the second function? It is not defined in global
space, therefore it is not a global variable, yes? Even if it was
global, how would it get from one function to another? In PHP
variables are copied by value. Are they copied by reference in
Javascript?
<SCRIPT LANGUAGE="JavaScript">

I want to write code that can be compiled as C and C++. In the Windows
API, there are many macros that help with scope resolution. For
example:
#ifdef __cplusplus
#define SNDMSG ::SendMessage
#else
#define SNDMSG SendMessage
#endif

I have a piece of code in which I pass a function to a function and it works fine in stand alone code but when I encorporate it in a class my compiler tells me there is no matching function. The error message is:
test.C: In member function ‘void Field::Evaluate()’:
test.C:29: error: no matching function for call to ‘Field:: Diff(double&, <unknown type>)’
test.C:18: note: candidates are: double Field:: Diff(double, double (*)(double))

Hi,
Is it possible to have a class level namespace opening instead of
file level .
Something like this,
I have a long namespace like
namespace com { namespace my_company{ namespace my_project{ namespace

Hi guys,
Is there a way to return a functor from a recursive call that takes
different paths? Let's say that I have a tree structure like:
root

first child ---- nextSibling ----nextSibling ----nextSibling
---->0

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...

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

Hello
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...
