A link list has 1 pointer point to the next. The Double link list has 2 pointers, one point to the Next and one point to the previous (its neighbors).
Memory in stack will be clear when exit the function and memory automatic de-allocate while the Heap is a memory will store in memory as long as user de-allocate it i.e. malloc and free. Stack is smaller in size, but faster than Heap.
