Hello,
I have a problem with using a copy constructor to convert an object of a
templated class to object of another templated class. Let me first
include the code (my question is below):
<code:templates.h>
#include <string>
#include <iostream>

I have tried to implement the overload of these 2 operators.
ostream & operator<<(ostream &out, Person &p){
out<<p.getName()<<" "<<p.getSurname()<<", "<<p.getDateOfBirth()<<endl;
return out;
}
This overload work but I have a curiosty
If I try to approch to the name or to the surname or to the dateofbirth in
this way i receive error:
ostream & operator<<(ostream &out, Person &p){
out<<p.name<<" "<<p.surname<<", "<<p.dateofbirth<<endl;

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?
// --------- foo.cpp ---------
#include <iostream>
using namespace std;

Hi. I'm using GCC 4.1.1, which I mention since I don't know
if this is a compiler issue, or me not understanding some
subtlety in the standard.
The code below compiles fine under vc++, but I'm having trouble
using gcc. It's just a templated container output.
/**
outputs elements of a vector in the form '{el1,el2...elEnd}'

>From a book, I know the following is true for the comparison operators:
An overloaded operator that is a class member is only considered
when the operator is used with a *left* operand that is an object
of that class.
And is that also the reason why if you use class member functions for
operators << and >you have to write:
someclass << cout;
someclass >cin;
?

I have some classes which have a "writeTo()" function
but no operator<<. I want to fix it so that they
all have an operator<< (for consistency).
Can I do something like this:
template <class T>
DataDest& operator<<(DataDest& d, const T& t)
{
t.writeTo(d);

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,...
