Hi.
Just as we have AVG(COLUMN_NAME) and MAX(COLUMN_NAME) how can I write
my own variation of a such a function. If I can appreciate how to do
this,
then I hopefully I can write a MEDIAN(COLUMN_NAME) type function or a
more general function like a 10% percentile function with syntax such
as
PERCENTILE(COLUMN_NAME,25).
Regards JC......

In Microsoft's help literature, it states:
"You can filter out non-unique rows by using the DISTINCT option of an

I am trying to do this in Access 2003 with the COUNT aggregate
function, but there is no reference, at least that I can find anywhere,
of how to do this. I have multiple lines fields for which I would like
to do a "count distinct", but for simplicity, I am showing an example
of only one field. Here is...

I need help writing a function for a program that is based upon the various operations of a matrix and I keep getting a "non-aggregate type" error. My guess is that I need to dereference my pointers, but I'm not sure. Please help.
The code:
void equate(matrix *A, matrix *B)
{
int i, j;
assert(A.row_dim == B.col_dim && A.col_dim == B.col_dim);
for(i=0; i < A.row_dim; i++)
for(j=0; j < A.col_dim; j++)

Hi i have been struggeling with this question for quite some time now.
I have some helper classes that handle images (upload an image, create
thumbnails and show a imagelist), links (add link, edit link, show
linklist), comments (add comment, show commentlist) etc.
I do not need all this functionality on every page.
Ideally I could just extend the controller like this

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...

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....
