Let me see if I got this :)
1. I know the rules for type conversions in arithmetic expressions
2. I know that an implicit type conversion is done at assignment, so
float x = 1.23;
int t = (int) x;
is equivalent to
int t = x;
(could the latter produce a warning on some complier?)
3. I know that implicit conversions take place with function arguments, but
am a bit shaky here. I suppose that passing a char to a function accepting

Could anyone please help me to understand what is happening here? The
commented line produces an error, which is what I expected given that
there is no conversion defined from type double to type Test. I
expected the same error from the following line, but it compiles fine.
The double is silently truncated to an int and then fed in to the
implicit conversion operator. Why does this happen? Is there any way
that I can keep the implicit...

Im trying to understand implicit type conversions from object -> string and
vice versa.
I have two classes, one Driver and one called StringWrapper. These are just
test classes that try and emulate the pattern im trying to follow in an
existing project.
These are my steps:
1) I have a method "printMe" existing in the application which originally
used to take in a string. This method is static and sits in the Driver

I have an implicit conversion set up in an assembly from a Stream to
something else. In C#, it works. In VB it does not.
Does VB support implicit conversions? And if so any idea why it would work in
a C# program but not VB?

Hello,
I can perform implicit conversion through constructor, like
class A{
public:
A(int x):a(x){};
int a;
};

Dear all,
I was trying to write a more complex program, and while searching for
sth in my reference C++ primer, by Lippman. I had a question in the
mind, see the code below

Hi, Is it possible to define a implicit operator from base to derived
types in C#?
I have a Point class and would like to derive a Vector class from it and
add a couple new vector related functions, like Normalize(). The problem
is Vector cannot use any of the Point operator overloads with a compile
time error that there is no implicit conversion from Point to Vector. I
tried adding an implicit operator to Vector:

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...
