You need to pair each new
with exactly one delete
. That is, you probably don’t want to delete prev
(this node already was deleted) but you want to delete value
. Well, I’d embed the value
into the object and not point to it:
struct node { node* prev; node* next; int value; };
If the value
absolutely needs to be a pointer, I’d use a std::unique_ptr<int>
(or, if you need to use C++ 2003, a std::auto_ptr<int>
).
