Tuples are defined with regards to parentheses ()'s as everyone knows.
This causes confusion for 1 item tuples since (5) can be interpreted
as a tuple OR as the number 5 in a mathematical expression
such as x = (5) * (4+6).
Wouldn't it have been better to define tuples with <>'s or {}'s or
something else to avoid this confusion??
Perhaps ()'s are a good idea for some other reason I don't know?

I'm following your help. I have written the overload of the operator <<.
This overload work! :-)
But I have some problem with the overload of the operator >>. I have written
the overload of this least operator for the class Person, but I don't know
how write the overload for a class that derived from the class Person.
The overload of << in Person is this:
ostream & operator<<(ostream &out, const Persona &p){
out<<p.getNome()<<"...

Member operators operator>>() and operator<<() in a program below
work fine, but look strange.
Is it possible to define member operators operator>>() and operator<<()
that work fine and look fine?

I'm trying to design an HTML page that can edit itself. In essence, it's
just like a Wiki page, but my own very simple version. It's a page full
of plain old HTML content, and then at the bottom, there's an "Edit"
link. So the page itself looks something like this:
<HTML><HEAD><TITLE>blah</TITLE></HEAD><BODY>
<!-- TEXT STARTS HERE -->
<H1>Hello World!</H1>
<P>More stuff here...</P>

Are the bitwise operators >>, <<, &, |, ~, ^ only defined for
non-negative values?
The little program below produces the output
3 255
I expected to get the 3 but why does it produce the 255 when the
variable c is not typecast first?

The following code snippet does not seem to work correcly
unsigned __int64 result = 0xFFFFFFFFFFFFFFFF;
result = result << 64;
Debugger.WriteLine(System::String::Format(S"{0:X16}", __box(result));
result = 0xFFFFFFFFFFFFFFFF;
result = result >> 64;
Debugger.WriteLine(System::String::Format(S"{0:X16}", __box(result));
__int64 result = -1;

Hi,
I'm trying to figure out the purpose of these operators.
Now, I know what they do. They shift bits either left or right.
But I don't know why would anybody want to do that. I've never seen
anyone using it in his/her code.
Any ideas?
Thanks,
Ben

Hi all,
I know it is possible to overload the operators and < in C++ but how
can I do this.
Assume I have a class Date with three int members, m_day, m_month and
m_year. In the .cpp files I have defined the < and operators;
bool Date::operator<(const Date& d)

Hi, in TC++PL 3 on pages 674-675 it is mentioned:

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...

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...
