1. ► Queue can be implemented using a list
2. ► Stacks have LIFO ordering
3. ► STL stack uses deque to implement stack
4. ► A queue has FIFO ordering
5. ► Nested function calls form a stack
6. ► Only top element can be accessed in stack
7. ► Accessing top element in stack is constant time operation
8. ► priority_queue’s priority function cannot be changed
9. ► An element of the priority queue can be accessed only in O(n) time
10. ► priority_queue forms the basis of many algorithms
