本文实例讲述了C++队列用法。分享给大家供大家参考。具体如下：

#include <iostream>#include <queue>using namespace std;int main(){ queue<int> one; one.push(1); one.push(2); one.push(3); cout<<"one 队列长度："<<one.size()<<endl; cout<<"队尾元素是："<<one.back()<<endl; cout<<"队头元素是："<<one.front()<<endl; cout<<"队列是否为空(1为空，0为非空)："<<one.empty()<<endl; one.pop(); //删除是从队头元素开始的 cout<<one.front()<<endl; cout<<one.size()<<endl; //cout<<one.top()<<endl; //普通队列好像没有次方法 //优先队列的使用 优先队列中使用back、front 出现错误 priority_queue<int> three; three.push(10); three.push(20); three.push(30); cout<<"three 优先队列长度："<<three.size()<<endl; cout<<"队列是否为空(1为空，0为非空)："<<three.empty()<<endl; while (false == three.empty()) { cout<<three.top()<<endl; three.pop(); } cout<<endl; system("pause"); return 0; }

希望本文所述对大家的C++程序设计有所帮助。
