C++ 提高编程 queue容器

 

 

 

 

#include <queue>
#include <string>
class Person
{
public:
    Person(string name, int age)
    {
        this->m_Name = name;
        this->m_Age = age;
    }

    string m_Name;
    int m_Age;
};

void test01() {

    //创建队列
    queue<Person> q;

    //准备数据
    Person p1("唐僧", 30);
    Person p2("孙悟空", 1000);
    Person p3("猪八戒", 900);
    Person p4("沙僧", 800);

    //向队列中添加元素  入队操作
    q.push(p1);
    q.push(p2);
    q.push(p3);
    q.push(p4);

    //队列不提供迭代器,更不支持随机访问    
    while (!q.empty()) {
        //输出队头元素
        cout << "队头元素-- 姓名: " << q.front().m_Name 
              << " 年龄: "<< q.front().m_Age << endl;
        
        cout << "队尾元素-- 姓名: " << q.back().m_Name  
              << " 年龄: " << q.back().m_Age << endl;
        
        cout << endl;
        //弹出队头元素
        q.pop();
    }

    cout << "队列大小为:" << q.size() << endl;
}

int main() {

    test01();

    system("pause");

    return 0;
}
