STL 中stack和queue依据deque的实现UML图

#include <iostream>using namespace std;class deque{public:    void push_back(int x){         cout<<"deque push_back"<<endl;    }       void push_front(int x){         cout<<"deque push_front"<<endl;    }       void pop_back(){        cout<<"deque pop_back"<<endl;    }       void pop_front(){        cout<<"deque pop_front"<<endl;    }   };class sequeue{public:    virtual void push(int x)=0;    virtual void pop()=0;};class stack:public sequeue{public:    void push(int x){         pdeque.push_front(x);    }       void pop(){        pdeque.pop_front();    }private:    deque pdeque;};class queue:public sequeue{public:    void push(int x){        pdeque.push_back(x);    }    void pop(){        pdeque.pop_front();    }private:    deque pdeque;};int main(int argc, char *argv[]){    sequeue *pseq_one = new stack();    sequeue *pseq_two = new queue();    pseq_one->push(1);    pseq_one->pop();    pseq_two->push(1);    pseq_two->pop();    return 0;}
