Hi, what is the different between the following two ways to use const
in a function definition:
1. const Array &operator=(const Array &);
2. int getSize() const;
keyword const to the left of return type and to the right of the
parameter list, what is the different here? I know for the 2nd case,
the function can not modify the object's data member.

Hi all and thanks again in advance,
What is the best way of defining global constants in a C# application? (A
windows application with no windows forms - basically a set of classes).
Would it be a wise idea to create a clsCommonApp and let all other classes
to be derived from that class? and define all constants in that base class?
Any other suggestions are more than welcome. (BTW this is not for one
constant, I have multiple...

Hi There!
I'm trying to define constants so that I can refer those constants from any
page of my ASP.NET website. I know I can use <appSettings> in web.config XML
file but I don't want to parse and read the whole XML document everytime a
page is requested.
In classic ASP, I used Include files and define constants using Const
keyword so that every page that has been included the file can refer the
constants.

What is the difference between 'const' and 'define()' ? When would I
prefer using 'const' over 'define', or vice versa? It seems if i do:
const secondsInMinute = 60;
define("secondsInMinute", 60);
Aren't these two the same thing?

Dear all,
the following are the differences b/w #define and typedef ,which i
have seen in Peter van der lindens book. is there any other difference
between thes two ?
The right way to think about typedef as being a complete encapsulated
type - you can't add to it after you have declared it.

I'm new to C++/CLI and my main background is Java. I'm trying to
create an array of constants as a static member of a class. An
example is shown below:
public ref class TestClass {
public:
static const array<constant int>^ stuff = {1,2,3,4,5};
};
This gives me compiler error C4538 which basically says that you can't

Hi,
I have a question on constant variables. In the following code
snippet, I have a function assign() that takes in an iterator to the
private variable v, the number of stuff to assign (int n), and the
information to assign (a const pointer to a class object
Vector<TYPE>.
According to the arrow below, I put a const keyword in the function.
To my knowledge, this means that all private variables in this object

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,...
