STL：C++标准容器库deque

 他是一个双向队列，大部分内容和vector基本一致

 主要是需要注意它是双向的，可头插，可尾插

int main()
{
        deque<Student> deq_stu;
        deq_stu.push_back(Student("lisi",22));
        deq_stu.push_back(Student("wangwu",53));
        deq_stu.push_back(Student("zou",29));
        //头部插入
        deq_stu.push_front(Student("ziwen",23));
        //头部删除
        deq_stu.pop_front();

        vector<Student> vec_stu;
        vec_stu.push_back(Student("lisi",22));
        vec_stu.push_back(Student("wangwu",53));
        //查找
        deque<Student>::iterator it;
        it = search(deq_stu.begin(),deq_stu.end(),vec_stu.begin(),vec_stu.end(),cmpname);
        if(it != deq_stu.end())
        {
            cout<<"found"<<endl;
           it->showStu();
        }
        else
            cout<<"not found"<<endl;

        it = search(deq_stu.begin(),deq_stu.end(),vec_stu.begin(),vec_stu.end());
                if(it != deq_stu.end())
                {
                    cout<<"found"<<endl;
                   it->showStu();
                }
                else
                    cout<<"not found"<<endl;
}
