hello guys. i need to build GUI. what do you recommend using?
Dima
It’s immediate though
Dima
But it’s cool
Dima
“Dear Imgui” is full name
Pavel
yes

“Dear Imgui” is full name
that's also a cool thing, but not sure how scalable it is
I want to integrate it to my game for debug menus

Imgui is great for that tbh...
Dima
Well my choice is “dear imgui”
Asad
what about sfml
Dima
GitHub repo
Pavel
what about sfml
as far as I know (again), with sfml you'll need to write your own gui library as it only gives you low level tools for that

Hi, in C, how do you open a file for writing whereby you can seek and replace bytes in-place? I'm looking at these docs and neither of the write modes preserve existing contents.

if i have a difficult computational problem, does it make sense to use threads?
Noor
Dima
what?
Nameful
I like Rust's naming convention
Nameful
C doesn't have one though, no?
Dima
I am using c# convention in c++ code lol

I am using c# convention in c++ code lol
Doesn't VC++ provide the C++ stdlib in PascalCase even?
Dima
¯\_(ツ)_/¯ I don’t use vc++
Dima
c++/cli
Nameful
What compiler do you use?
Dima
pure c++, not vc++ or cli
Dima
got addicted to that convention after looking at UE4’s code
Dima
clear, readable
Jagadeesh
Rules ?

hi

anyone know about the size of virtual inheritance class
Anonymous
Anonymous
in this case size(classB) is 24, but after removing char a, size(B) is 8
Anonymous
I'd appreciate it if someone could help me out
Avezy
Padding Bytes maybe
Anonymous
but the size is 24 and 8, if it is padding, it should be at most 16
Avezy
Optimizer playing tricks maybe youve got two times vptr + padding If the Compiler Cannot optimize it

Just Look at it in Compiler explorer

thanks! so it depends on my compiler

struct X{
map<int,X*> mp;
};
void fun(X* root){
root->mp[6] = new X;
}
int main(){
X *root = new X;
fun(root);
}
1. Wanted to ensure that, on the call of fun(X* root), root->mp[6] resides in heap and the newly created X is also in heap. So, a pointer in heap points to something on heap.
2. Does delete(root->mp[6]) deletes the the newly created object?
Asad
anyways. this concept makes a lot of sense

It's ugliest

Use smart pointers
Ajay
BTW, what's the problem using new and delete here
Anonymous
In modern C++ in most cases manually managing memory with new and delete keywords is bad practice

didn't get the term "manually managing memory" in this context. Can you point it out?

What are you trying to achieve in first place?
This code smells

Google what smart pointers are
Anonymous
And how to use them
Anonymous
And why using new and delete is bad
