Hello,
I couldn't find an obvious answer to this in the FAQ. My basic question,
is: Is there any difference in allocating on the heap versus the stack? If
heap or stack implementation is not part of the standard, then just
disregard this question. Here's some questions I'm confused about, and if
you can add anything else, please do so!
Is the stack limited for each program?

using the following code, i was able to have my compiler seg fault on
me when i gave the argument as anythng greater than 20,832,000bytes. In
the case of the struct its 868 instances of said structure. The
compiler obviously allows VLA however it craps out after the above
amount of bytes.
I was told i was attempting to put everythng on the stack and not the
heap. So i was wondering if anyone can maybe clear it up, is that true?
would i...

I'm reading Eric Gunnerson's book.
He is talking about the heap and stack, he says you have 2types, value
wich are in the stack or inline or reference types wich are in the heap.
I don't get this what's heap stack and what's the main difference
between those 2types ?

I had an interview today and I got destroyed :(
The question was why have a stack and a heap?
I could answer all the practical stuff like value types live on the
stack, enums are on the stack, as are structs, where classes are on
the heap... when value types go out of scope the memory is re-
allocated, object remain in memory waiting to be cleaned up by the
garbage collector, etc, but he responded 'so why not just put say a
class on the...

Hi all,
I need a few clarifications regarding memory allocaion in C++.
I apologize for the lengthy explanation.
1. In C++, Objects are allocated in heap.
What does heap refer to? Is it an area in RAM/Memory or does it refer
to a data structure being used for storing objects.
2. In C++, functions and its local variables go in stack.
If local variables that are primitives go in stack, it is OK. But what

This is an interview question and I gave out my answer here, could you
please check for me?
Q. What are the memory allocation for static variable in a function,
an automatic variable and global variable?
My answer: static variable in function and global variable are
allocated in head, and automatic variable is allocated in stack.
Right?

Thanks everybody for helping me with the Syntax confusion! The
implicit conversion stuff really got me :) I have one more
question...
Array<int32ia;
Does the above use the default constructor and get me an Array<int32>
with a size 0? The memory used is the stack, right?
ia = Array<int32>(10);

Hello,
I'm confused about heap and stack memories management in C language. Most
books explain that local stack variables for each function are automatically
allocated when function starts and deallocated when it exits. In contrast,
malloc() always takes memory in the heap. Now, let's consider the code as
follows:
int get_buffer()

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...

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

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...

In this session, we are pleased to welcome a new presenter, Adolph Dupré who will be discussing some powerful techniques for using class modules.
He will explain when you may want to use classes instead of User Defined Types (UDT). For example, to manage the data in unbound forms.
