priority_queue: default to sort the queue as 6.5.4.3, greater stands front

if we wanna ascending order, using__

priority_queue<int, vector<int>, less<int> > pri_que;

#include <iostream>
#include <list>
#include <vector>
#include <queue>
using namespace std;

int main ()
{
int tmp[] = {1,2,3,4};
priority_queue<int> q1(tmp,tmp+4);
priority_queue<int,vector<int>,less<int> > pq; //default to greater
q1.push(1);
q1.push(6);
pq.pop();
cout<<q1.top()<<endl;

pq.size();
pq.empty();
return 0;
}
