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?

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 have a question related to allocating on the stack.
In this program below, are my following assumptions true?
- variable a is allocated on the heap since it's static
- variable b is allocated on the stack since it's a value type variable
- variable d is allocated on the stack since it's a value type variable
Where does variable "c" get allocated? It's a value type, but not foundwithin a method.

General Info:
A struct is stored on the stack and a class on the heap.
A struct is a value type while a class is a reference type.
Question:
What if a struct contains a string property(variable). The string would
be a reference type being contained in a value type. Would this filter
up and cause the stack to now be a reference type placed on the heap
or would it still be on the stack with a pointer used internally to point
to a...

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

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,...

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...
