Hi all!
How does Python pass arguments to a function? By value or by reference?

Hello Experts!!
This class template and main works perfectly fine.
I have this class template called Handle that has a pointer declared as T*
body;
As you can see I have a reference counter in the class template so I know
how many references I have to the body. In my case it's the Integer wrapper
class which is the body.
This template works for many different types.
The one that I use is named Integer and is a Wrapper for an int. The...

Hi all,
I am trying to make a vector containing objects the have a reference
member. However, as soon as I try to push_back an element into this
vector, g++ balks at the fact that it needs to instantiate an operator=
on the class containing the reference members (see below for what I try
to do).
#include <vector>

Hi,
I noticed in Python all function parameters seem to be passed by
reference. This means that when I modify the value of a variable of a
function, the value of the variable externally from the function is
also modified.
Sometimes I wish to work with "copies", in that when I pass in an
integer variable into a function, I want the function to be modifying
a COPY, not the reference. Is this possible?

Hi everyone:
I am reading Bjarne Stroustrup's The C++ Programming
Language(Special Edition).
In section 7.3, bs wrote "Like the semantics of argument passing,
the semantics of function value return are identical to the semantics
of initialization. A return statement is considered to initialize an
unnamed variable of the returned type."

Can we confirm the following? also someone said, Java also has
"reference" like in C++, which is an "implicit pointer":
Pointer and Reference
---------------------
I am starting to see what pointer and reference are and how they
relate
to each other.

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.
