I'm doing a simple project for school. This is the first time I've
ever used Access.
Is there a way i can simulate a Circular Queue data structure for the
datas in a table. I tried assign index and use sorting, but the
problem is that i will have new data enqueued very often, and the
sorting will not simulate the CIRCULAR Queue.
Can any one suggest a way of doing it with query, VB, or SQL?

I have this cute data structure that I just found a second opportunity
to use. I googled for references to it, but came up empty. I
probably just don't know its name.
The algorithm on this data structure typically has an array of
pointers, and in a loop refers to array .. array,
modifies array, then increments i. I do away with i by having
an array of size 2*n, where array = array. Then I use array2
instead of array, increment...

Working with implementing a circular buffer for a producer/consumer deal.
Have not done one in a while. The following seems to work. However, I
remember and have seen other implementation that make the buffer 1 more then
the needed capacity so that a full buffer and an empty buffer can be
differentiated. However this implementation does not do that (i.e. the
capacity and the buffer size is the same.) I assume the following does not...

Hi,
I want a circular buffer or queue like container (queue with array
implementation).
Moreover I want random access over the elements. And addition at tail
and remove from head need to be low cost.
STL vector is suitable for removing form tail? or it is as costly as
removing from middle?
any other std container to serve this purpose? (note , I dont need
linked list implementation of any container, as I want random access)

Hi there,
I have to write an optimized circular buffer to log events in C++. The
elements are of type std::string. This should run under Linux on an ARM
embedded system. I can dedicate to this circular log a preallocated
block of fixed size and work in there.
Can anybody indicate me an example or technique to do this ?
Thanks
Marco

When define a maxQueue is 10, means it able to store 10 items in circular queue,but when I key in the 10 items, it show "Queue Full" in items number 10.
Where is the wrong in my code? Why it cannot store up to 10 items?
Output from my code:
Enter you choice: 1
Enter ID document to print : 21
Enter you choice: 1
Enter ID document to print : 22

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,...
