C++

Let head be a pointer that points to a linked list with a certain number of nodes. What happens in a call to: delete head; ?

1)All nodes in the list will be freed.

2)The first node on the list will be freed but the rest will just be lost, generating a memory leak.

3)Nothing. The language takes care of not allowing to delete the head if it points to a list.
