For a variety of reasons, I'm interested in putting together some
code that will allow me to created structures out of nested classes,
something like:
class class1:
def methA(self):
print "Some code here"

Dear all
I have an Object that I will call for instance VEHICULE. This object
contains some other type of objects like CAR and BICYCLE
VEHICULE has necessary at least one object of type CAR or BYCICLE
My question is that if I am at the VEHICLE lass level, it can contains a
certain amount of CAR class and BICYCLE class.

Hello All,
When is nested class more preferable that Inheritance ? I think with proper
inheritance and friend class concept we can get the same flexibility as nested
classes
Any comments ..
Best Regards

Hi All,
I use VS2003 and managed code to compile a DLL.
When I use a nested class, the event always cause an error:
LINK : error LNK2020: unresolved token (06000004)
Test.TestClass::OnEventFired
LINK : fatal error LNK1120: 1 unresolved externals
If I remove the nested class, everything goes fine.

Hi,
I am very interested to know which one of the two functions below is
used more often by people. The 1st way intends to let B prepare the
data and A perform the action. The 2nd way intends to let A initialize
data in a general way and B specialize the data. My question may be
dumb because it depends on needs. But I am preparing a huge class
structure without knowing every small details now. I wonder if I can
formalize a rule in...

Hello,
I have a problem trying to figure out the following design issue. I have a
base class and a number of classes derived from that base. A method in the
base class covers 90% of the functionality required for all classes, however
I need to have that 10% functionality that is left in the derived classes.
What I would like to do is have the method in the base class be able to call
the method in the derived classes, it should do this...

I just started to learn C++. I copied the following code from a data structure textbook to a ".h" file and couldn't compile it. The code contains three template interfaces. One inherits another. The functions in the interfaces are defined in book, while the nested-class part is added by me. The reason is that if I don't declare a nested class, say Position, how could it be passed as arguments to those defined functions? However, it seems that...

Suppose there is the following class structure.
class S {...}
class A : S {...}
class B : S {...}
class A1 : A {void m(){...}}
class B1 : B {void m(){...}}
class B2 : B {...}
Just to clarify the issue. A1 and B1 share a
method (void m() ) AND B2 doesn't have that

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,...
