I'm having a problem understanding why the code in this little program
I've got is behaving the way it does... if anyone can explain it, I'd
be grateful:
#include <iostream>
using namespace std;
//This function takes an unsigned char (one byte on my machine)
//and prints it in binary notation

I'm getting tired of the following error message.
Compiler Error message : Error: Need explicit cast to convert
from: float
to: float *
I am trying to use a routine from the Numerical Recipes library called
amebsa.c. The routine requires several parameters of the following
form. *iter, **p, *yb.... . How does one initialize these variables?
If I declare them as pointer (in this case, *yb and *iter) the
compiler still tells me that it...

Hi,
I have a problem to implemente the strategy pattern. the problem come
from that a method take different arguments type (object in interface
and String / Int in implemented class).
When price3 instance call getPrice, the method invoked is the one of
PriceRule abstract class. But, I want to invoke the method of
PriceruleForRegion. So I think the solution is somewhere on casting to
original type (PriceRuleForRegion) but I don't how I...

Hi all, I just discovered a rounding error that occurs in C#. I'm sure
this is an old issue, but it is new to me and resulted in a fair amount
of time trying to track down the issue.
Basically put the following code into your C# app:
float testFloat2 = (int) (4.2f * (float)100);
Console.Out.WriteLine("1: "+testFloat2);
and the result will be 419

Hello all,
First of all, sorry for multiple question per one thread. I have two
questions. First what I think might be the easier problem. I am
capturing data from an embedded device which I need to display data.
One particular piece of data is a 32 bit floating point value. The
problem I am having is converting the 4-byte value which is read via
an RS-232 link. How can I cast the 4-byte value to a value type float
correctly? I have...

Dear Experts,
I need a function that takes a float, swaps its endianness (htonl) in
place, and returns a char* pointer to its first byte. This is one of a
family of functions that prepare different data types for passing to
another process.
I have got confused by the rules about what won't work, what will work,
and what might work, when casting. Specifically, I have an
implementation that works until I remove my debugging, at which...

Hi ,
I was going through peter van der linden's book Expert C programming,
in this book there is a section named "How and why to cast"
the author then says as follows
(float) 3 - it's a type conversion and the actual bits change.
if you say (float) 3.0 it is a type disambiguation,and the compiler
can plant the correct bits in the first place.some people say that

Hello all,
I have "PRECISION" defined in the preprocessor code
and it could be int, float or double, but I do not know in the

Now if I want to assign zero to a "PRECISION" variable,

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,...

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....
Now, this would greatly impact the work of software developers. The idea...

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...
