Memory allocation

[Taxidriver]

Hello, supposing I have a structure like this:

struct node {
int data;
struct node *next;
}

if I define a pointer called *node that points to an object of the type "node" how much space should I allocate to the pointer and how that value is calculated?

Thank you.

You need to allocate enough memory to hold a struct node.

struct node *node=malloc(sizeof *node);

The sizeof expression is the same as calculating sizeof(struct node).
