The default base container for queue is deque. You can also specify list as a base container, but you cannot specify vector, because it lacks the required pop_front member function.ExampleCopy // queue_queue.cpp // compile with: /EHsc #include <queue> #include <vector> #include <list>...
( 10 ); // but the following would cause an error because vector has // no pop_front member function // q3.pop( ); // Declares a queue with list base container queue <int, list<int> > q4; // The second member function copies elements from a container list<int> li1; li1.push...
concurrent queue or blocking queue implemented in cpp Guide introduction Whereproduce-consumerpattern is present it is often the case thatone is faster that the other: a parsing producer reads records faster than a processing consumer; a disk reading producer is faster than network sending consumer....
The queue must be nonempty to apply the member function. The top of the queue is the position occupied by the most recently added element and is the last element at the end of the container.ExampleC++ Copy // queue_pop.cpp // compile with: /EHsc #include <queue> #include <iostream>...
The member function returns an array containing the controlled sequence. You use it to obtain a copy of the controlled sequence in array form.ExampleC++ Copy // cliext_queue_to_array.cpp // compile with: /clr #include "pch.h" #include <cliext/queue> typedef cliext::queue<wchar_t> My...
