"#define" can only be inside the global scope before main() function.
"#if" can be tested after "#define" is executed. The problem is that
"#define" can't be inside main() function. I do not wish to create multiple
functions which they look almost identical in C++ source code. The C++
compiler should be able to compile one Test() function into two almost
identical functions before they are translated into the machine language
object. ...

Hi!
I'm using an IplImage library from camellia.sourceforge.net, and the
testbench calls a file only containing code like the one below. In
cam_morphomaths_code.c the real computation is made, but I don't
understand where cam_morphomaths_code.c is included and how to set
what parameters to use in the testbench.
How does this code execure? I don't understand a bit...

Hi all,
I have the below #defines
#define NUMBER1 30
#define NUMBER2 50
#define SUM (NUMBER1+NUMBER2)
#define STRING1 "Byte: \x30"
#define STRING2 "Byte: \x50"
If I change NUMBER1 and NUMBER2 I must change STRING1 and STRING2
consequently.

Hello
Is there a way to declare 'FUNCT' via a define so that if its parameter x, a constant, is
greater than 35, it returns 56, if not, 20.
I would like that at compile time, not at run time.
So:
#define FUNCT(x) x>35?56:20

Where is the best place to define TRUE and FALSE?
Are they in any of the standard include files, ever?
Do any standards apply?
What I've traditionally done is something like:
#ifndef (TRUE)
#define TRUE (1)

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,...
