The std::queue class is a container adapter that gives the programmer the functionality of a queue - specifically, a FIFO (first-in, first-out) data structure.

The class template acts as a wrapper to the underlying container - only a specific set of functions is provided. The queue pushes the elements on the back of the underlying container and pops them from the front.

Template parameters

T	-	The type of the stored elements.
Container	-	The type of the underlying container to use to store the elements. The container must satisfy the requirements of SequenceContainer. Additionally, it must provide the following functions with the usual semantics: back() front() push_back() pop_front() The standard containers std::deque and std::list satisfy these requirements.

Member types

Member type	Definition
container_type	Container
value_type	Container::value_type
size_type	Container::size_type
reference	Container::reference
const_reference	Container::const_reference

Member functions

(constructor)	queue의 생성자이다. (public member function)
(destructor)	queue의 소멸자이다. (public member function)
operator=	컨테이너 어댑터에 값을 할당한다. (public member function)
Element access
front	첫번째 요소에 접근한다. (public member function)
back	마지막 요소에 접근한다. (public member function)
Capacity
empty	현재 컨테이너가 비어있는지 확인한다. (public member function)
size	원소의 개수를 반환한다. (public member function)
Modifiers
push	inserts element at the end (public member function)
emplace (C++11)	끝에 원소를 바로 만들어 삽입한다. (public member function)
pop	removes the first element (public member function)
swap	원소들을 서로 바꾼다 (public member function)
Member objects
Container c	the underlying container (protected member object)

Non-member functions

operator== operator!= operator< operator<= operator> operator>=	lexicographically compares the values in the queue (function template)
std::swap(std::queue)	specializes the std::swap algorithm (function template)

Helper classes

std::uses_allocator<std::queue> (C++11)

specializes the std::uses_allocator type trait (function template)
