问题描述

如何从优先级队列中删除所有元素？这意味着如何销毁优先级队列？
高级感谢您的回答。是否有清除或擦除方法？

How do I delete all elements from a priority queue? That means how do I destroy a priority queue? advanced thanks for your answer. Is there any clear- or erase-like method?

推荐答案

priority_queue接口没有clear没有好的理由，我曾经能够辨别）。清除它的简单方法只是分配一个新的空队列：

The priority_queue interface doesn't have a clear() method (for no good reason I've ever been able to discern). A simple way to clear it is just to assign a new, empty queue:

priority_queue <int> q;
// use it
q = priority_queue <int>(); // reset it
