The address of i would not change because it's incrementing the value, but of what I've learnt pointers are pointing to addresses and incrementing them would change the address

it is a local variable, why would the address of local variable change after incrementing a value of the variable?

k now try this
int arr[5]; // i know it's uninitalised, who cares
for (auto iter = std::begin(arr); iter != std::end(arr); ++iter) {
std::cout << &iter << ' ' << iter << ' ' << *iter << '\n';
}
(can't do std::cout << iter on an std::list::iterator because as Danya said, iterators are not pointers. so the example uses an ordinary array)

The reason i doesn't change its address is the same for it

T* pointer = {any pointer value};
const auto pointer_address_before_incrementing = &pointer;
pointer++;
pointer_address_before_incrementing == &pointer; // true
That's an axiom

Hi there, do anybody knows how to disable WindowTitleBar (title, and navigation buttons panel) but not WindowBorder (that grants ability to resize window) I've tried to manipulate with SetWindowLong(), but only the GWL_STYLE, 0 implements that I want (somehow), it also disable WindowBorder, I don't want to code "new" resize events for undecorated window like i did in java, so is there a way to hide only WindowsTitleBar ?

If there is an abstract class Shape, and 2 classes Rectangle and Triangle, deriving Shape, should the functions be always declared in Shape even if there is one member function that is used only by Rectangle and not by both?

Hi, wrote stuff with select(), but I am running into weird failures…
Since I have no idea where the problem is, I'll send my entire code (it's not that much):
https://hastebin.com/ujuhijexax.cpp
The code exits with:
accept: invalid argument
in line 118 when connecting
However when I remove line 145, it suddenly works as expected!
Sometimes clients[x].recv_queue.size() (and other elements in the struct) causes that error, sometimes it doesn't. Same about adding other stuff affecting the clients map
Any idea?
Dima
nice name lol

Even changing length of strings in code can either fix or get me the error back

Hello, i have list of vectors. list<vector<int>> l; i know there is no random access in list. But is there any way to randomly access elements of vector provided the list iterator(like l.begin()). I have googled. But they used a for loop to access within vector. Is there a way for random access
Hello
Can someone help me with this

Are you saying you want a random element of the vector?
Hello
Thanks, found (*(l.begin()))[0]

i'm trying to rotate elements in a vector, when i get output in above case "2" is skipped and 1 and 3 are pushed behind.
First, the element in the index 0, which is 1, is erased:
vect: 2, 3, 4, 5, 6, 7
Next time, the element in index 1, which is 3, gets erased:
vect: 2, 4, 5, 6, 7

if(secim == 1){
fseek(dosya1, 0, SEEK_SET);
while(!feof(dosya1)){
char ch;
fscanf(dosya1, "%c", &ch);
//fseek(dosya1, -1, SEEK_CUR);
fprintf(dosya1, "%c", ch + 17);
}
}
Why is that code infinite loop?
Emir
fscanf +1
fseek -1
fprintf +1
why?

Someone's is knowledgeable about *C++* ? I have basic assignment questions to solve but since I'm unaware about the subject. Can anyone solve them for me? I can *pay* for your work. Ques Set is 1. 🙏🙏🙏🙏

Hello
I read Non static member initialization is introduced in c++11 which allows to initialize directly like
class A{
int data{1};
};
So was this an error to use
class A{
int data =1;
};
Before c++11?
Are both codes refer the same feature introduced in c++11
