这是c++编程方面的名著的例子代码

template <class Container>
class stack {
friend bool operator==(const stack<Container>& x, const stack<Container>& y);
friend bool operator<(const stack<Container>& x, const stack<Container>& y);
public:
    typedef Container::value_type value_type;
    typedef Container::size_type size_type;
protected:
    Container c;
public:
    bool empty() const { return c.empty(); }
    size_type size() const { return c.size(); }
    value_type& top() { return c.back(); }
    const value_type& top() const { return c.back(); }
    void push(const value_type& x) { c.push_back(x); }
    void pop() { c.pop_back(); }
};
