Hi,
I'm a newbie to C++ (2 weeks into the course). We were given this
assignment to write some code that reads a set of integers (grades)
from a file (filename passed by console), outputs them in reverse
order, calculates and prints their average.
=> We have been told that we need to make sure that our code meets
"information hiding" guidelines. Could anyone help me get started with
this (any ideas?)

Hi,
I'm learning C# and I just don't quite understand the need for
polymorphism. why do we need to use it? how does a base class variable
holding a derived class instance do any good?
Also, what's the difference between method hiding and overriding when
they're both still overriding the base method.
Thanks

Hi all.
I am trying to figure out the differences between
overriding and hiding a method name.
The only difference i can see, is that with name hiding i can change
the method access level.
Are there any other differences?
Thanks, Sharon.

Hi,
I know there exists a good reason why the designers of c++ decided that
function hiding should exist. But I don't know why. Can anybody provide
a good reason/example of a case where function hiding saves the day. I
know there exists one, I'd just like to hear about it.
thanks and have a nice day.

Hello NewsGroup,
I have a base class and six classes that inherit from this base class. All
members in the base class are used in it's extended classes except, in one
of the extended class one member in the base class is not required. Is it
possible to mark a method in the extended class such that it does not appear
in that particular extended class?
I know you can use the 'new' keyword and redefine the method with a
'private'...

Hi all,
I have been wondering for a while why function hiding (in a derived
class) exists in C++, e.g. why when writing
class Base {
void foo( int ) {}
};
class Derived: public Base {
void foo( char const ) {}
};

Hi all
I'm developing a control, and I need to hide some properties to the
user. For example, suppose I need Text property to be completely
inacessible (from a Form/Code that is into another project/assembly).
I tried with attributes:
<Browsable(False), _
EditorBrowsable(EditorBrowsableState.Never), _
RefreshProperties(RefreshProperties.Repaint), _

Hi
I have a question regarding this concept I learned about recently:
Name Hiding. Here's what I've come across:
There is a base class with two functions with the same name but
different signature. A class inherits publicly from this base class
and redefines one of the two functions in the derived class. In that
case, a derived class object cannot access the other base class
function that it hasn't redefined. I'm posting a code snippet...

Hi,
first, python is one of my fav languages, and i'll definitely keep
developing with it. But, there's 1 one thing what I -really- miss:
data hiding. I know member vars are private when you prefix them with
2 underscores, but I hate prefixing my vars, I'd rather add a keyword
before it.
Python advertises himself as a full OOP language, but why does it miss
one of the basic principles of OOP? Will it ever be added to python?

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:

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...
