Standard C++ Library Class Reference

Equality operator. Returns true if x is the same as y.
template <class T, class Allocator>
bool operator< (const deque<T, Allocator>& x,
const deque<T, Allocator>& y);
Returns true if the elements contained in x are lexicographically less than the elements
contained in y.
template <class T, class Allocator>
void swap (deque<T, Allocator>& a, deque<T, Allocator>& b);
Efficiently swaps the contents of a and b.
Example
//
// deque.cpp
//
#include <deque>
#include <string>
deque<string, allocator> deck_of_cards;
deque<string, allocator> current_hand;
void initialize_cards(deque<string, allocator>& cards) {
cards.push_front("aceofspades");
cards.push_front("kingofspades");
cards.push_front("queenofspades");
cards.push_front("jackofspades");
cards.push_front("tenofspades");
// etc.
