// g++ std-deque.cpp -o a.out -std=c++11
#include <iostream>
#include <deque>

using namespace std;

int main() {
    deque<int> d = {1, 2, 3, 4};  // [1, 2, 3, 4]

    d.push_back(5); // [1, 2, 3, 4, 5]
    d.pop_front(); // [2, 3, 4, 5]
    d.push_front(0); // [0, 2, 3, 4, 5]
    d.pop_back(); // [0, 2, 3, 4]

    // 印出 deque 內所有內容, c++11 才支援
    for (int &i : d) {
        cout << i << " ";
    }
    cout << "\n";

    cout << d[0] << " " << d[1] << " " << d[2] << "\n";

    return 0;
}

deque c++

Comment

/*  A deque is a dynamic array whose size can be efficiently 
changed at both ends of the array. Like a vector, a deque provides
the functions push_back and pop_back, but it also includes the 
functions push_front and pop_front. */
deque<int> d;
d.push_back(5); // [5]
d.push_back(2); // [5,2]
d.push_front(3); // [3,5,2]
d.pop_back(); // [3,5]
d.pop_front(); // [5]
