I keep getting the error 'Use of unassigned local variable' in my code,
which I have used before and it works fine :

I am instantiating a class in a switch statement as there are a number
of different overloads depending upon the data entered by the user.
The problem I have is that after instantiating my class, when I try to
call methods in the class later on in my code using the same object I
cannot, I get the error 'use of unassigned local variable'.
How do I get around this as I need some sort of switch/if statement to
instantiate my class?

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...

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,...
