Hi,
Pretty simple one I think...Is there a "power of" or squared function in
C++. This is what i'm trying to achieve.
(array-array)*2
this doesnt work with minus numbers so i need a square or power function.
also.. Is there a "sum of" function. Ultimately i'm trying to do a euclidean

I just want to raise a number to a power.
e.g.:
16^2
The pow()-function of cmath seems to be not enough. I've read
about valarray. Is it really so difficult?
Can you give me an example.
Thanks Roman

Hi I am using this function to power numbers
int power (int m, int n);
int power (int base, int n) {
int i,
p;
p = 1;
for (i = 1; i <= n; ++i)
p *= base;
return p;

Hi there,
Is there a way to convert a double value to a string. I know that there
is fcvt() but I think this function is not a part of the standard
library. I want sth from the standard if possible.
The thing I am trying to do is to convert a double value to a string
with 8 elements. 8 is fixed because of the files I work with. I will
change this 8 character string with the one(8 character string) already
in the file and so on. But I...

not implemented in the framework Math library.
Does anyone have some code lines how to create an own Power function?

hi,
i develeoped a recursive function for the power and it works fine
double power(double x, int n) {
if (n < 0)
return 1/power(x, -n);
else if (n == 0)
return 1.0;

Hi all,
Need the community great support once more. :)
I need to know how to calculate the power of some numbers in C, the problem is that the number is too big , and the compiler gives a error when doing the arithmetics.
See the power function I am using:
unsigned long int power(int base, int n)

Our machines have this requirement: if power failure occurs, many
important variables are to be resumed from where they were interrupted
after the machine is restarted (power on in this case). In other words,
the basic idea is to keep a snapshot of the state machine before it is
interrupted.
The board is provided with:
- a 32-bit H8S/2633 Hitachi microprocessor;
- a battery-backed memory (BBM), where these variables are stored; BBM

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,...

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....

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...
