We can insert or delete elements from both side in this structure. Here we will see some C++ code using dequeue STL to understand its functionality. Example (Dequeue) Live Demo #include <iostream> #include <deque> using namespace std; void dequeElements(deque <int> que) { deque <int> :...

Stacks and Queues are two of the most important data structures in programming: A Stack has two main operations: Push: Pushes an element into the stack Pop: Returns the last element that was put into the stack The Stack'...

Philip A. Bernstein, Eric Newcomer, in Principles of Transaction Processing (Second Edition), 2009 Generalized Messaging We have focused on using queued messages for the reliable processing of requests and replies. However, queuing can be used for other kinds of messages too. That is, the enqueue...
