那要怎样？

追答

queue
template >
class queue {
public:
typedef Cont::allocator_type allocator_type;
typedef Cont::value_type value_type;
typedef Cont::size_type size_type;
explicit queue(const allocator_type& al = allocator_type()) const;
bool empty() const;
size_type size() const;
allocator_type get_allocator() const;
value_type& top();
const value_type& top() const;
void push(const value_type& x);
void pop();
protected:
Cont c;
};
The template class describes an object that controls a varying-length sequence of elements. The object allocates and frees storage for the sequence it controls through a protected object named c, of class Cont. The type T of elements in the controlled sequence must match value_type.

Answer 2

#include<queue>
using namespace std;
