Hi all,
I have noticed that I over and over again write member functions which
iterate over vectors and other containers.
Is there a standard way of doing this, like assigning a template
function to a range of container iterators?
<example code>
//show the eventui vector
int y = 20, v_interval = 20;

Hello,
It is not possible to assign values to, say, a vector<float> due to the
fact that arrays are not assignable.
Theoretically there's a simple workaround which involves wrapping the array
in a struct, e.g.
struct float3
{
float m;

Hi,
in my program, I have to sort containers of objects which can be 2000
items big in some cases. Since STL containers are based around copying
and since I need to sort these containers quite frequently, I thought
it'd be a better idea to manage additional containers which are
initialized with pointers to the objects in the primary containers and
sort those (only pointers have to be copied around then).
However, that also means if I...

I'm trying to write some C code, but I want to use C++'s std::vector.
Indeed, if the code is compiled as C++, I want the container to
actually be std::vector, in this case of a collection of value types or
std::vector<int>.
So where I would use an int* and reallocate it from time to time in C,
and randomly access it via , then I figure to copy the capacity and
reserve methods, because I just need a growable array.
I get to considering...

Just a simple theoritical question to the experts.
What was the rationale behind making STL containers follow copy
semantics rather than reference semantics. References almost always
make things easier without much of overhead. Then why not reference ?
Thanks

HI
If I define the class DoubleMap such that
struct DoubleMap : public std::map<std::string, double>{};
Is there any overhead in calling std::map member functions ?
Moreover are STL containers destructors virtual >

I've read with much interest the threads on how to create data
containers in C.
I started thinking if simpler ADT (other than the proposed List) could
be used as a starting point.
What about a dynamic vector? I mean a dynamic array with no predefined
size. A possible API could be:
typedef struct {

Why doesn't the C standard include generic function pointers?
I use function pointers a lot and the lack of generic ones is not so cool.
There is a common compiler extension (supported by GCC and lccwin32 for example)
which I consider to be perfectly reasonable: you can cast every kind of function pointer
to a void pointer and void pointers to any kind of function pointer.
This follows the general "generics through void scheme" of C....

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.
