Hi -
I've been reading the posts for a solution to my query, and realize
that I should ask an "approch" question as well.
We receive our production data from a third party, so my uers import
the data from Excel into the appropriate tables. There are 6
different databases that receive data, though 4 of them only get one
table each.
I have learned how to automate the data import through

Hello-
i am trying to make the function addbitwise more efficient. the code
below takes an array of binary numbers (of size 5) and performs
bitwise addition. it looks ugly and it is not elegant but it appears
to work. using time, i measured it takes .041s to execute, which i
admit isnt much. but, the problem is that this procedure will be
called many, many times in my project (probably at least a few
thousand times, if not more) so...

Hi all,
Normally, I would trust that the ANSI libraries are written to be as
efficient as possible, but I have an application in which the majority of
the run time is calling the acos(...) method. So now I start to wonder how
that method, and others in the math.h library, are implemented.

I have a function that is called very very often.
Can I improve its efficiency by declaring its local variables to be static?

Hi,
I have read somewhere that C code sometimes cannot be compiled to be as
efficient as FORTRAN, eg for matrix multiplication, because a C
compiler cannot make the assumptions about arrays that a FORTRAN
compiler can. But I don't understand the example, not least because I
don't understand FORTRAN. I also don't understand why it is more
efficient in this case for a compiler to choose the order of evaluation
(or whatever it is that it...

dynamic_cast can be used to obtain a pointer or to obtain a reference.
If the pointer form fails, then you're left with a null pointer.
If the reference form fails, then an exception is thrown.
Would "Feed1" or "Feed2" be preferable in the following:
#include <iostream>

Hi,
Is there any group in the manner of the C++ Boost group that works on
the evolution of the C language? Or is there any group that performs an
equivalent function?
Thanks,

Hi all,
This is a question about the efficiency of the code.
a :-

for( i = 0; i < 20; i++ )
printf("%d",i);
b:-

Efficiency
I've never stumbled on any discussion of efficiency of various methods of coding, although I have found posts on various forums where individuals were concerned with efficiency. I'm not concerned when dealing with user typing, but I am if a procedure is called by a query.
Does the VBA compiler generate "in-line" code for some apparent function calls? For example, y = Abs(x) might be compiled as y = x & mask. The string...

For OO design, I like using virtual member function.But considering
efficiency, template is better. Look at this program,

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,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
