A have a long integer class. The built integer type within a conditional
statement returns bool false for int i=0 and bool true for any other non
zero value. I want my long integer class to have similar behavior. My
class looks like this:
#ifndef long_int_H
#define long_int_H
#include <string>
using namespace std;
typedef valarray<complex<double> > VCD;

The following may strike many of you as just plain silly, but it represents
the kind of delelima I find myself in when trying to make a design
decision. This really is a toy project written for the purpose of learning
to work with C++. It therefore makes some sense for me to give the
situation the amount of consideration presented below. To be quite honest,
I'm amazed at the amount there is to say about such a seemingly simple...

Hi,
I was wondering if there is any way to make two objects of the same
class to be able to access each other's private data, like this:
class A {
public:
void access( const A& a ) {cout<<"a.value="<<a.value<<endl; }
private:
int value;

Hi,
Why didn't the committee propose a new type for complex numbers with
integer components?

This seems strange, but maybe there's some basic concept I'm missing.
When I assign one class member to another, any methods that are applied
to one are applied to both variables.I can't get the code below to work
(display sum, product and quotient) without re-initializing z1 each
time. What's the problem here?
Dim z0 As Complex = New Complex(CDbl(Me.TextBox1.Text),
CDbl(Me.TextBox2.Text))
Dim z1 As Complex = New...

I'd like to get output formatting for my own classes that mimics the
built-in output formatting. For example,
>>> x = 4.54
>>> print "%4.2f" % x
4.54
In other words, if I substitute a class instance for "x" above, I'd
like to make the format string apply to an element or elements of the
instance. Can I somehow overload the "%" operator for that? Thanks.

I'm taking in data from multiple files that represents complex numbers
for charateristics of different elements. I begin with arrays of
doubles and interpolate to get standard values in real and imaginary
portions. To this end I have some dynamic arrays of doubles to hold
the standardized individual rael and imaginary parts.
double *ANreal, *ANimag, *BNreal, *BNimag, *CNreal, *CNimag;
ANreal = new double;
ANimag = new double;

The C99 standard forgot to define the printf equivalent for complex numbers
Since I am revising the lcc-win implementation of complex numbers
I decided to fill this hole with
"Z"
for instance
double _Complex m = 2+3*I;
printf("%Zg\n",m);

ONU (Optical Network Unit) is one of the key components for providing high-speed Internet services. Its primary function is to act as an endpoint device located at the user's premises. However, people are often confused as to whether an ONU can Work As a Router. In this blog post, we’ll explore What is ONU, What Is Router, ONU & Router’s main usage, and What is the difference between ONU and Router. Let’s take a closer look !

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,...

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....
Now, this would greatly impact the work of software developers. The idea...

In this session, we are pleased to welcome a new presenter, Adolph Dupré who will be discussing some powerful techniques for using class modules.
He will explain when you may want to use classes instead of User Defined Types (UDT). For example, to manage the data in unbound forms.
Adolph will...

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...
