Question

Here is my data structure

struct Node{
      int x;
      Node *next;
      Node *prev;
}

If I allocate memory

Node *A = malloc (sizeof (Node) * 10);

How can I access each box in the array using array index in this case? or it’s not possible?

My goal just want to make a linked list in this chunk of memory.

basically i want to assign a block of memory and then assign their prev and next….

maybe it’s confusing , sorry about my wording..

Answer 1

This gives you an array of 10 Nodes, accessible through A. Now, all you have to do is e.g.

A[0].next = &A[1];

to set the next value of the first node.
