Writing a LinkedList destructor?

Question

Is this a valid LinkedList destructor? I\'m still sort of confused by them.

I want to make sure I\'m understanding this correctly.

 LinkedList::~Link         


        

Answer 1

Your code might be correct, you should try running it with e.g. valgrind and see what it says. However, I would write it like this:

for (ListNode *current = head, *next; current; current = next) {
    next = current->next;
    free(current);
}
