I am writing code to read an xml file. I want two values from the document
so I want to save them as I am reading through the elements. I want to
reference them (using Console.WriteLine) after I complete the loop. When I
compile I get the "use of unassigned local variable".
What am I doing wrong?
stripped down code:

I understand that if I don't assign a *local* variable before I use it, the
compiler will generate a "Use of unassigned local variable" error. What I
don't get is why doesn't the compiler just implicitly assign a default value
to my unassigned variable?
At this point you are getting ready to reply to me and tell me that this is
just a way for the compiler to protect me from introducing a possible bug by
preventing me from forgetting to...

In the following (pseudo)code, why is it that C# returns an
"unassigned local variable" error for nVar? It seems I have to
declare the variable outside foo() for the error to dissapear.
void foo()
{
int nVar = 0;
SqlDataReader rdr = objCmd.ExecuteReader();

Use of unassigned local variable 'fs'
Please see where I've indicated where the compiler is flagging this error in
the method below. fs is initialized in the first line in the try block, so
why is it flagged as unassigned in the finally block?
Thanks for your help!

In the following example, c# 2.0 compiler says that a3 and ret are used
before assigned.
as far as I can see, definite assignment is made.
If I add
finally
{
ret = true;
a3 = "b3";

This is a little tricky, but I think the error I'm getting isn't
valid. The compiler just doesn't know my logic.
MyObject o;
switch (IntVariable)
{
case 1:
o = new MyObject()
break;

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...

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...
