Little question

So in my C++ book, when the guy create a structure, he always create a pointer of the type of the structure, just like this...

Code:

struct Familly { int members; int parents; Familly *nextFamilly; }

Something like this... Can someone explain me why this is useful?

Linked List...

If he is using that without telling you what it is. I'm going to say that you are reading a crappy book.

I talk a bit about linked lists here:
