Hi All,
I use new to allocate some memory,even I doesn't use delete to release them.
When my Application exit, OS will release them.
Am I right?
If I'm right, how about Thread especally on Solaries OS?
This means that I use new to allocate memory in one Thread and doesn't use
delete to release them.

Hi all,
I have couple of questions, I hope I can find the answers
here...(assuming the question are okay with this group)
A) what is memory alignment? I have a rough idea but cant clearly
understand it clearly...? If anyone has a pointer on net please tell
me.. I would be grateful...
Some told me that for memory to be aligned, the last 6 digits of the
address should be zero? is this correct?

I came across several possible ways of allocating memory for objects,
for example:
1. malloc(sizeof(T)*3)/free - raw memory
2. new T/delete - buffer would be initialized to
default-constructed T objects.
3. operator new(sizeof(T)*3)/operator delete - raw memory

I have a class A containing some map as data variables. I creat an
object of class A on heap by allocatiing memory by using "malloc". This
will return me the required memory but the object is not initialized
properly as constructor same is not get called ( as per the behavior).
How to call a constructor explicitly if we want to allocate memory
using malloc ?

I have read in Bjarne Stroustrup that using malloc and free should be
avoided in C++ because they deal with uninitialized memory and one
should instead use new and delete.
But why is that a problem? I cannot see why using malloc instead of new
does not give the same result.

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...
