The good news:
Along with Python-2.4 comes really good news to Windows users. Yes,
you now CAN build extension modules yourself using the SAME C++
compiler and linker Python is built with itself. Everything you need
is available at no costs (except download hassle and installation
time). Once your system is set up properly its just a matter of
running 'python setup.py build'. No longer waiting for someone else to
build binaries and a...

Hi,
Suppose there is a vector of objects of class A, i.e., std::vector<A>
vec_A(N); The class A satisifies all the STL vector requirements.
Now I wish to add some attributes for each of the objects in the
vector vec_A. Suppose there are K attributes to be added. For each of
the attributes I define K vectors of appropriate types. Say, the
attributes have types type1, type2, ..., typeK. So I define
std::vector<type1> attr1(vec_A.size());

I was reading through Accelerated C++ at work when I read through the first
mention of Vectors, giving us certain functions etc.
Is there any benefit of Arrays over Vectors? Since all Vectors seem to be
(in my eyes at least) are glorified Arrays.
- Now I know there's a bit more difference, but what exactly are the
advantages of Arrays over Vectors (if any)?
Oh, and please keep it in mind I am a real beginner in C++ but can

Hello.
I am having some problem organizing a set of vectors. The vectors itself,
could contain a pointer( say integer pointer) or could contain another
object MyClass.
1>So, first of all, is there anyway where I can accomodate both the vector
types into a single set. Something like a set<vector<void*>, my_compare func

Right now, I am having them as two different set dayatypes.

This might be more appropriate here. I'm new to C++, coming from a
background in another languages that allowed a similar solution to work
(Python). I wrote the following code in C++ based on the Python code
found here:

Hi.
I hope someone would be able to help me with this:
I need to declare a structure composed by a couple of vectors. But I need those vectors to have an open dimension, I mean non-especific size (for example: short vector) so that the user doesn't have to be tied under a maximun limit.
I'm using Visual C++, but the compiler won't let me use such a way of declaring a vector inside the structure (although I can do it provided it's not...

How would I do this?
I want to be able to handle vectors of many different types of data
and vectors that can contain any number of other vectors of data.
Currently, I have a templated function that handles vectors of vectors
of <typename T(which could be anything from int to vectors of
something else). As well, I have specialized/overloaded functions to
handle the single-level vectors of data (e.g. vector<string>). So the
templated...

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...

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.
