I've been using functions since I first started using php, but I've been
hearing more and more about classes, which I never really looked at that
much. I understand the whole OO programming aspect, but are there any
advantages to having classes as opposed to just functions? I've heard that
the classes are better because they only load the functions they need to,
where with an include file of functions, the whole page gets loaded, even

Hi,
Generally if I re-use code, I use a function. If I need to use these
functions over a number of pages I write the function to an include
file where all pages have access.
So when should I ever use PHP classes instead. I have learned how to
put together PHP classes but never seen a reason to use them where I
can simply use a function.

A few questions about the following code. How would I "wrap" this in a
function, and do I need to?
Also, how can I make the code smart enough to realize that when a file
has 2 or more bad charcters in it, that the code needs to run until all
bad characters are gone? For example, if a file has the name
"<bad*mac\file" the program has to run 3 times to get all three bad
chars out of the file name.
The passes look like this:

I'm not getting any feedback on the most important benefit in my
proposed "Ideas for Python 3" thread - the unification of methods and
functions. Perhaps it was buried among too many other less important
changes, so in this thread I would like to focus on that issue alone.
I have edited the Proposed Syntax example below to take out the
changes unecessary to this discussion. I left in the change of

I am still getting my head around a few base concepts. Any comments or
criticisms on the below definitions would be most welcome!
A function is an object.
JavaScript objects have properties:
- a var (which is an object or a primitive);
- a method (which is a function assigned to the object).

How to build or find an object browser for javascript?
E.g. Delphi integrated developement environment ('ide') offers a very
practical object browser for Pascal language. When typing a name with a
dot you get a list of objects,properties and methods to select from.
When you select or type a methodname or function and the left
parenthesis , the system writes the possible argument types. With key

I am not clear as to the best time to set a function as Shared and when not

Hello,
I learned that there are five kinds of static objects, namely
1. global objects
2. object defined in namespace scope
3. object declared static instead classes
4. objects declared static inside functions (i.e. local static
objects)
5. objects declared at file scope.

The implementation of classes with virtual functions is conceptually easy to
understand: they use vtables. Which begs the question about POD structs: how
are they associated with their member functions in common implementations?
And where is the 'this' ptr tucked away at for POD structs with member
functions?

Hello all,
I'm learning C and I still am struggling to understand some basic
concepts. For example, I read in the standard that with functions such
as strcpy, 'If copying takes place between objects that overlap, the
behavior is undefined.' But how can I be sure that they don't overlap?
For example, if I write this:
char string1 = "overlap";

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
