The header <queue> is part of the Containers library of the C++ Standard Library. It defines the container adaptors, the class templates queue and priority_queue, and a set of relational operators that C++ programs may use to perform equality and inequality tests on specializations of queue.

namespace std {
  template <class T, class Container = deque<T> > class queue;
  template <class T, class Container>
  bool operator==(const queue<T, Container>&, 
                  const queue<T, Container>&);
  template <class T, class Container>
  bool operator<(const queue<T, Container>&, 
                 const queue<T, Container>&);
  template <class T, class Container>
  bool operator!=(const queue<T, Container>&, 
                  const queue<T, Container>&);
  template <class T, class Container>
  bool operator>(const queue<T, Container>&, 
                 const queue<T, Container>&);
  template <class T, class Container>
  bool operator>=(const queue<T, Container>&, 
                  const queue<T, Container>&);
  template <class T, class Container>
  bool operator<=(const queue<T, Container>&, 
                  const queue<T, Container>&);

  template <class T, class Container = vector<T>, 
          class Compare = less<typename Container::value_type> >
  class priority_queue;
