Ok, I'm quite a newbie, so this question may appear silly. I'm using
g++ 3.3.x.
I had been taught that an array isn't a lot different from a pointer
(in fact you can use the pointer arithmetics to "browse" it). So I
expected that when I run this program, I get both c1.A and c2.A
pointing to the same address, and changing c1.A means that also c2.A
changes too.

Just a question/observation out of frustration.
I read in depth the book by Peter Van Der Linden entitled
"Expert C Programming" (Deep C Secrets). In particular the
chapters entitled:
4: The Shocking Truth: C Arrays and Pointers Are NOT the Same!
9: More about Arrays
10: More about Pointers
What blows me out of the water is the fact that 'every' programmer

This statement is legal C#:
public const string day = "Sunday";
but this statement is not:

The C# Programmer's Reference specifies that 'the only valid values of a constant declarator constant expressions'. A constant expression is defined as 'an expression that can be fully evaluated at compile-time ... Therefore, the only possible values for constants of reference...

I understand that structures are value types and arrays and classes are
reference types. But what about arrays as members of structures i.e. as in
C
struct x
{
int n;
int a;
}

Hi
From what I understand, you can pass arrays from classic ASP to .NET using
interop, but you have to change the type of the.NET parameter to object.
This seems to be because classic ASP passes a variant containing an array,
and interop expects a parameter of type object if you are passing a variant
(you are expected to cast it to the correct type in your code). I'd like to
find a way of passing arrays so that you don't need to change...

Hi,
I'm upgrading a VB6 app to VB.net and I'm having a problem with a call to a
function provided in a DLL.
The function takes the address of a structure which it will fill in with
values.
I get an error:

Hi. I'm more-or-less a C newbie. I thought I had pointers under control until
I started goofing around with this:
================================================================================
/* A function that returns a pointer-of-arrays to the calling function. */
#include <stdio.h>
int *pfunc(void);

Hello,
Could someone explain why the following code is illegal?
(I'm trying to use a list of (C-style) arrays.)
#include <list>
typedef std::list < int foo_t;
int main()
{
int v = { 12, 34 };

Why are the following declarations invalid in C?
int f();
int f();
It would be great if anyone could also explain the design decision
for such a language restricton.

Overview:
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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
