Fellow hackers,
I have a class BuildNode that inherits from class Node.
Similarly, I have a class BuildTree that inherits from class Tree.
Tree includes a member variable:
vector<Node> nodes; // For clarity, let this be "orig_nodes"
BuildTree includes a member variable:

I need to build the maze board(like 2d array) using a tree. But I find
that my buildTree function doesn't work. Could anyone give me some
hints on debugging it? Thanks

I am trying to determine how far I should go in encapsulating data. As I
understand it, OO practices state to create private member variables and use
these variables in your publicly accessible functions. This requires the
programmer to set the variables using the setters of the class before
calling the function. The problem that I see is that the coder doesn't know
the private variables needed by the public function without viewing the...

I have a class 'TagType' with an ilist member 'Props' that holds a
collection of another class called 'Prop'. I let the user create
TagTypes and save multiple properties (Props) in them.
I am having a problem storing a Prop object in a TagType object. The
code below is giving me a "Object reference not set to an instance of
an object." error. I don't understand why

I am trying to produce a singleton class that I can use throughout my
library to write tracing information to a file. My intent was to design
such that someone using the library in its debug mode would be able to
see what was happening without having to use a debugger to step through
each instruction. What they would do is run their program and view the
tracing file output. If there was something wrong then they would use the
debugger of...

Using VS 2003, I am trying to take a class that I created to create new
variable types to handle nulls and track changes to standard variable types.
This is for use with database variables. This tells me if a variable has
changed, give me the original and current value, and whether the current
value and original value is/was null or not.
This one works fine but is recreating the same methods over and over for
each variable type.

Hi,
I have a question on constant variables. In the following code
snippet, I have a function assign() that takes in an iterator to the
private variable v, the number of stuff to assign (int n), and the
information to assign (a const pointer to a class object
Vector<TYPE>.
According to the arrow below, I put a const keyword in the function.
To my knowledge, this means that all private variables in this object

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...
