The STL provides three container adaptors, called stack, queue, and priority_queue They utilize one of the sequence containers as the underlying container, adapting it to their own special purposes In essence, a container adaptor is simply a tightly controlled interface to another container Although the container adaptors are built on one of the sequence containers, they are, themselves, also containers and you use them much like you use the other containers It's just that access to their elements is restricted This recipe demonstrates their use Before we begin, an important point needs to be made The container adaptors do not support all of the functionality of their underlying containers The manipulations allowed by an adaptor are a highly restricted subset of what the base container supports While the precise restrictions differ from adaptor to adaptor, there is one difference that is shared by all: Iterators are not supported If the adaptors supported iterators, then it would be a trivial matter to circumvent the data structure defined by the adaptor (such as a stack) and access its elements out of order

To use the sequence container adaptors involves these steps: 1 Create an instance of the container adaptor, selecting the one suited to your application

2 Use the functions defined by the adaptor to insert, access, and remove elements from the container Each adaptor defines its own set of these functions For example, to push an element onto a stack, call push( ) To obtain the next element from a queue, call front( )
Discussion
The stack class supports a last-in, first-out (LIFO) stack Its template specification is shown here: template <class T, class Container = deque<T> > class stack Here, T is the type of data being stored and Container is the type of container used to hold the stack, which by default is deque The stack adaptor has the following constructor: explicit stack(const Container &cnt = Container( )) The stack( ) constructor creates an empty stack To use a stack, include the <stack> header The underlying container is held in a protected object called c of type Container In general, stack can adapt any container that supports the following operations: back( ) pop_back( ) push_back( ) Thus, you can also use a list or a vector as a container for a stack The stack class defines the functions shown here Notice that elements in a stack can be accessed only in last-in, first-out order This enforces its stack-like nature
Member bool empty( ) const void pop( ) void push(const value_type &val) size_type size( ) const value_type &top( ) cont value_type &top( ) const Description Returns true if the invoking stack is empty and false otherwise Removes the top of the stack Pushes an element onto the stack Returns the number of elements currently in the stack Returns a reference to the top of the stack
The queue class supports a normal first-in, first-out (FIFO) queue Elements are inserted into a queue on one end and removed from the other Elements cannot be accessed in any other fashion The queue template specification is shown here: template <class T, class Container = deque<T> > class queue

Here, T is the type of data being stored and Container is the type of container used to hold the queue, which by default is a deque The underlying container is held in a protected object called c of type Container The queue adaptor has the following constructor: explicit queue(const Container &cnt = Container( )) The queue( ) constructor creates an empty queue To use a queue, include the <queue> header In general, queue can adapt any container that supports the following operations: back( ) front( ) pop_front( ) push_back( ) Thus, you can also use list as a container for a queue However, you cannot use vector because vector does not provide the pop_front( ) function The queue adaptor defines the functions shown here As you can see, they restrict queue to providing only first-in, first-out access to its elements
Member value_type &back( ) const value_type &back( ) const bool empty( ) const value_type &front( ) const value_type &front( ) const void pop( ) void push(const value_type &val) size_type size( ) const Description Returns a reference to the last element in the queue Returns true if the invoking queue is empty and false otherwise Returns a reference to the first element in the queue Removes the first element in the queue Adds an element with the value specified by val to the end of the queue Returns the number of elements currently in the queue
The priority_queue class supports a single-ended priority queue A priority queue arranges its contents in order of their priority The priority_queue template specification is shown here: template <class T, class Container = vector<T>, class Comp = less<typename Container::value_type> > class priority_queue Here, T is the type of data being stored Container is the type of container used to hold the priority queue, which by default is a vector The underlying container is held in a protected object called c of type Container Comp specifies the comparison function object that determines when one member is lower in priority than another This object is held in a protected member called comp of type Compare
