I'm currently working on a small project (admitedly for my CS class)
that compares the time difference between passing by value and passing
by reference. I'm passing an array of 50000 int's. However, since in
C++ an array is passed by reference by default I need to embed the
array into a struct in order to pass it by value. The problem is that
I get a segmentation error when doing so. I'm using the Dev-c++
compiler. Any ideas?

Hi,
I am designing an application where to preserve the hierachy and for
code substitability, I need to pass an array of derived class object in
place of an array of base class object. Since I am using vector
class(STL), the compiler does not allow me to do this.
I do realize there is a pitfall in this approach(size of arrays not
matching etc), but I wonder how to get around this problem. I have a
class hierachy with abstract base...

Can someone please help, I'm trying to pass an array to a function, do some
operation on that array, then return it for further use. The errors I am
getting for the following code are, differences in levels of indirection, so
I feel it must have something to do with the way I am representing the array
in the call and the return.
Below I have commented the problem parts.
Thanks in advance for any help offered.

Hi,
In the attached example, I do understand that the references are not changed
if an array is passed by Val. What I do not understand is the result of line
99 (If one can find this by line number) which is the last line of the
following sub routine:
' procedure modifies elements of array and assigns
' new reference (note ByVal)
Sub FirstDouble(ByVal array As Integer())
Dim i As Integer

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...

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,...
