I need a general mechanism for passing parameters to an API function I
am designing, call it foo. Foo processes data, the operation used to
process the data and the parameters for that operation are to be
passed to foo. A simple approach involves the use of base and derived
classes:
Class DataProcessor
{
Public:
enum ProcessorTypeEnum{op1, op2, op3}

"The C++ Programming Language" by Bjarne Stroustrup, copyright 1997 by AT&T,
section 4.8 (pp 77):
"A value of integral type may be explicitly converted to an enumeration
type. The result of such a conversion is undefined unless the value is
within the range of the enumeration. For example:
enum flag { x=1, y=2, z=4, e=8 }; // range 0:15
flag f1 = 5; // type error: 5 is not of type flag
flag f2 = flag(5); // ok: flag(5) is of type flag and...

Any opinions or comments on the following? I don't say it below, but I came
out on the side of using enumerations over static constants.
/* I'm trying to figure out the pros and cons of using static const
* int class members as opposed to using enumerations to accomplish a
* similar goal. The use of static constants seems more explicit and
* obvious to me. Unless I assign values to the enumerators, the
* compiler will do it for me....

I know that string/char enum is not possible in c# (.NET2.0)
I need to create the equivalent of this:
public enum HOW_GOOD
{
AWESOME = "A",
GREAT= "G",
NOT_TOO_BAD = "N",
TERRIBLE="T"
}

Hi Everyone,
I have writing a class that represents a object on a screen. The object has
normal things like X,Y, Width, Height, ZOrder, and it also has drawing
attributes and flags.
It has properties for setting and getting values from instance variables
that represent the above attributes of the class.
For the flags, which are bit values, I have 3 methods, one for setting, one
for removing and one for testing for the flags.

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
