What is the difference between these two?

Question

class node{
public:
int data;
node* next;
};

1. struct node* new_node = (struct *) malloc(sizeof(struct node));
2. node* new_node = new node();

I have been seen tutorials using the first one to allocate memory, but I'm using the second one without any problem.

Answer 1

As I understand it, (1) is dynamic memory allocation in C way, and (2) is the C++ way.

The (2) calls for a constructor, one that matches given argument(s), or the default constructor where no argument was given, e.g. `new node()`
