Declaring an array inside typedef struct

Question

I'm trying to declare an array inside a typedef struct like this:

typedef struct Node {
     Node[] arr = new Node[25];
};

But I am getting an error saying "expected an identifier" and that arr "expected a ';'. What am I doing wrong? Thank you

Answer 1

you can act like this

struct Node {
    static const int arr_size = 25;
    Node* arr;
    Node() { arr = new Node[arr_size]; }
    ~Node() { delete[] arr; }
};

you re not allowed initialzie non const int varizbles inside the class;

and do you understand, that creating a node variable will call stack overflow ? Each node contains 25 nodes where each node contains 25 nodes ... etc

---

i think you wanted something like this

struct Node {
    static const int arr_size = 25;
    Node* arr[arr_size];
};
