Can anyone clearly explain the difference between constant reference to
pointers and reference to constant pointers?
What is const int * & ?
Is it a constant reference to a pointer to an integer? Or
Is it a reference to a pointer to a constant integer?
What is being constant in this case? The pointer or the integer being pointed?
How about int * const & ?
Is this a reference to a constant pointer to an integer? Or

Hi all,
In the following code the line *(int *)&i = 11; is confusing to me.
What is it doing ?
#include<iostream>
using namespace std;
int main()
{
const int i = 10;
*(int *)&i = 11;

Given following code snippets:
int a;
int* p=(int*)((&a)+1);
when I debuged the code using IDE like VC7.1, I found that:
a = 0x0012fc50 (int )
p = 0x0012fc78 (int *)
(&a)+1 = 0x0012fc51 (char *)
(&a)+2 = 0x0012fc52 (char *)

Hi,
I am a little confused about & and int &. Do they both mean reference?
int a;
int* b= & a ; (& here mean reference of a)
int& b = a ; ( How to understand & precisely here?)
Thanks in advance,

Turning algs for old NumPy modules into numpy code I suffer from this:
Upon further processing of returns of numpy calculations, lots of data in an apps object tree will become elementary numpy types.
First there is some inefficiency in calculations. And then you get data inflation and questionable dependencies - e.g. with pickle,ZODB,mpi's ... :

MS VS 7.0 happily resolves by SmartPointer and Inheritance, but I got
to use another target compiler and it does not accept user conversion
for templates. Can I forced a recast somehow? I have judiciously
checked almost all constructs with both compiler before coding, but
during a heavy session, I forgot to check the user conversion part,
and now, I am stuck big time :(
So here is my user conversion for a smart pointer class (direct...

Hello, everyone! I am trying to optimize some code, but I don't think
I'm doing what I think I'm doing. I profiled my code and found that
the overloaded operator of my monomial class did
6384690328 calls in 33.67 seconds.
33.67 6384690328 Monomial::operator(int) const
Since the parameter was an int, I made it const int& since I reasoned
I would be saving a copy of the int parameter to the stack by changing
from a pass-by-value to...

I've been banging my head against an interaction between a table and float element.
I want the two of them to together take up 100% of the width of their container. If the table cells' content were to wrap around the float, even better, but that's not necessary.
However, I'm continuously running into two issues:
1.) If I make my table 100%, it writes over the float: right for tables where the content text is long enough.
2.) If I...

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...
