class A
{
public:
static A* newA() { return new A; }
....
};
In the code, two things not very clear and natural to me:
1. the method newA() is defined as static.
2. newA as a member method of class A IS returning a "new" instance of A

Hi,
I am new to C++. I want to directly create a dynamic two-dimension
double array, i.e. double pp. I found the "new" is only for
one-dimension array, i.e. double *p = new p. How to
"new" a two-dimension array?
Is the only way to create a class?
In java, I can easily create a two-dimension array by "double pp =
new double". But, how to do it in C++?

Rookie c++ question, but Ive spent the last 5 years doing Java, where
everytime I created an object I used new. In c++ I can create my objects
without and its confusing me just a little.
I have a class called polynomial. Its a nothing little class right now,
with just int variables, a basic container class. Im using it as I go
through some tutorials, but in this particular tutorial its telling me to do
polynomial *first = new...

25 years ago every computer came with some form of Basic interpreter
so you could use yoru computer without having to buy more software. Is
Javascript (teamed with HTML) set to become the new Basic, where
anyone with a computer can start writing code without having to
purchase any expensive languages?

I know STL vector works. But in case STL is not available,
what can one do to allocate large memory size in c++ through
operator "new"? For instance, I am writing a sort algorithm, and
here's part of the code:
const int range = 1000000;
int *array = new int(range);
if (array == 0) cout<<"null ptr returned"<<endl;

i see serveral source codes , and i found they almost only use "new"
and "delete" keywords to make they object.
Why should i do that , and as i know the object is going to be destroy
by itself at the end of the app
for example:
class test
{
public:
int x;

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,...
