I know at least 2. The first where you allocate a big chunk of memory, and then you fill the same way you would push elements on a stack. And when the big chunk is full, you allocate another big chunk and you either make a linked list of those big chunks or you store ..

I am learning Qt to do a certain project, I found this code online. I want to try it but I get an error "allocation of incomplete type ‘Ui::Paint’" in the .cpp file. this is the header file Paint.h #ifndef PAINT_H #define PAINT_H #include <QWidget> #include <QTimer> #include <QResizeEvent> #include <paintscene.h> namespace Ui { class ..
So I am trying to understand the state of the memory when I run the below code. From my understanding, the two sub-trees left and right that are initialized within the if-statement should be considered non-existent once the if-block ends. However, when I run this code, the output from within the if-block is the same ..
i am always getting 10861 segmentation fault (core dumped) in c++ sorry i came from java it always says that head -> next how to allocate memory to that #include <iostream> using namespace std; class Node { public: int data; Node *next; }; class lisp { public: Node *head; void create(int d) { this->head->data = ..
Say we have this component object. struct Component{ int data; }; Consider these two approaches a class have a component. class Entity_Heap{ //only a pointer contributes to sizeof(Entity_Heap) Component* HeapComponent = new Component; }; class Entity_Inline{ //what is the proper way to talk about this allocation? //it isn’t always actually on the stack… inlined memory? ..
Is there an existing way to disable every code’s lines of a logger depends on log_level without surrounding every call by an ifndef ? // 5 debug // 4 info // 3 warning // 2 error // 1 fatal My problem is that even with a log_level set to 3 for exemple, only the warning ..
I’m new to C++ and I’ve been playing around with memory allocation lately. I have found out that when you declare a class with a destructor, like so: class B { public: ~B() { } }; And then create a heap array of it like so: B* result = new B[8]; The allocator allocates 12 ..
I am creating a dynamically typed programming language and I need to resolve how I will allocate memory for the objects. Every size of an object is a multiple of 8 and is guranteed to be bigger than 16. I have tried malloc() and new but it is really slow. The code will run on ..
I want to store int[] inside B and store B[] inside C. There are also other fields that act the same way. In a certain run-time situation, I know that all vector (.bf1,.bf2,.cf1,.cf2 and cs) that created in a code scope must have certain size (e.g. num_bf1,num_bf2,num_cf1,num_cf2 and num_c). #include <iostream> #include <vector> class B{public: ..
