Dear All,
I want to know how a subroutine should return an array of values to
the main program.
From the main program, I call a sub-routine 'get_sql' which then
fetches data from oracle db using oci8 routines. The output resides in
a structure defined within the sub-routine. Now I want this structure
to be returned to main program so that I can assing output data to
variables in main program and do some manipulation. Can any body guide...

Thanks to all those who responded. Your tips really worked. So I will
give a simple program to explain, how I did it.
#include<stdio.h>
void update();
struct fields
{
char f1;
char f2;
char f3;

I'm calling one stored procedure with a prepared statement on the
server with 6 arrays of around 1200 elements each as parameters. The
parameters are around 220K in total.
This is taking a surprising amount of time. Thus I put a lot of logging
into the application and in the stored procedure that's getting called.
It seems that almost all of most of the time is spent before the stored
procedure is even entered.
What wakes my suspicion...

Hello,
I understand that if an array is illegal in some particular context,
then its name will be converted to a pointer. For example, if
int a = {1,2,3};
then a function
void f(int* a);

I am quite new to c++, about half of a year.
I juct wonder, why such code is not possible:
int chlen(char * ar) {
for(int i=0;ar||return i;i++);
}
In my opinion, it would be much "cuter" than this:
int chlen(char * ar) {

Why are the following declarations invalid in C?

It would be great if anyone could also explain the design decision
for such a language restricton.

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,...

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....
