Hi,
I have always been taught to use an inialization list for initialising data
members of a class. I realize that initialsizing primitives and pointers use
an inialization list is exactly the same as an assignment, but for class
types it has a different effect - it calls the copy constructor.
My question is when to not use an...

Hey guys, need some help understanding some things that maybe someone can
explain or clarify it a little better then a text book. Here is my
understanding so far:
Class - basically a shell for your code
Fields - basically just a variable but can be "write protected"
Properties - access fields, they can retrieve data contained in the...

Are there any reasons that would make it bad for C++ to
allow simultaneous declaration and initilization of member data?
Current way:
------------
class DerivedClass : BaseClass {
{
enum { lengthSV=16 }; // Length of SomeVector
vector<double> SomeVector;

Hi all
I have code for an object factory, heavily based on an article by Jim Hyslop
(although I've made minor modifications). The factory was working fine using
g++, but since switching to the Intel compiler it has stopped working. I
think the singleton pattern static instance thing may be at the root of the
problem, but I'm not sure. I had...

The oder of member initialization is the order in which the members are
defined.
So the following code is problematic:
class X{
int i;
int j;
public:
X(int val):j(val),i(j){}

Hi,
Where is the proper place to use a member initialization list, the
header or cpp file?
Does it make any difference?
Also, is there any difference between using a member initialization list
and initializaing member variables in the constructor?

Why would anyone write:
class SomeThing // class littered with non-domain single-instancing code :(
{
private:
SomeThing();
static SomeThing* pInstance_;
public:
static SomeThing* getInstance()

Is it possible to implement member object's virtual functions, in the
containing class? If not, is it possible to simulate this behavior?
ex:
class test
{
protected:
virtual void fun() = 0;
};

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. ...

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.
