I've been converting some code to C++. I'm trying to use the Switch
function to compare a result. Is it possible to use switch to evaluate
'>0', '<0', 0?
Example
switch (result)
{
case (>0):
case (<0):

C++ programmers and I tried to experience by writing 65536 switch
cases. It is too large for Windows XP and other operating system to
handle. It looks like that JMP Table obtains 256K bytes for 65536
switch cases. The program would crash when it attempts to run.
C++ Compiler does not support above 64K switch cases. I tried to
set a limit to 2048 switch cases and 4096 switch cases, but the
problem exists when program crashed again.

hello. i've been beating my head against a wall over this for too
long.
setting the variables 'z' or 'y' to differing numbers, the following
'if/else' code snippet works fine; however, the 'case' code snippet
does not. (the code's function is illustrative.)

Hello,
I have to write a program for an 8051 micro-controller using micro-C to
monitor Switch 1 and if the switch in pushed the message "switch 1
pushed" should be displayed in the LCD. Also the microcontroller
should display in the LCD the value of the voltage applied to the input
of the ADC.
The above procedure should only execute once the user has entered
"1234" using a keypad that is attached to the 8051 microprocessor.

Hi,
I am using FileStream's Async API: BeginRead/EndRead, upon completion callback execution I use the read data and call EndRead, Taking that in mind, I Wonder... does calling EndRead will cause a context switch? What is the kernel object used for blocking EndRead calls? Event and mutex cause a context switch even when the object is signaled and no wait is needed, usage of critical section prevent this switch from happening... what is the...

Hi
i have a string variable which can take one of a set of many values.
Depending on the value I need to take different (but related) actions. So I
have a big if/else-if construct - but what is a better way of doing this?
if ("control" == commandString)
{
}
else if ("execute" == commandString)

Just wondering if the sequence of the case(s) in the switch block might
impact performance. Suppose I switch on an int, and I have 4 expected cases.
Lets say I expect case 3 to happen 95% of the time. Would the switch block
be expected to execute faster (meaning "start executing the code for case 3
sooner") when case 3 appears first, as opposed to appearing as the 3rd
case:, as in the following code?
switch (someInt)
{
case 3:

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,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

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...
