如何設定順序容器

#include<iostream>#include<string>#include<vector>#include<deque>#include<list>//各种顺序容器的常见操作
//vector  list dequeusing namespace std;int main()
{    vector<int> a;    const vector<int> ca;//常迭代器
    list<int> b;    deque<int> c;

    a.push_back(10);
    a.push_back(20);
    a.push_back(30);

    b.push_back(100);
    b.push_back(200);
    b.push_back(300);

    c.push_back(1);
    c.push_back(2);
    c.push_back(3);    for (vector<int>::size_type i = 0; i < a.size(); ++i)
    //int可能不够大,可能超过i的范围
    {        cout << a[i] << endl;
    }    ////list链表没有下标
    //for (list<int>::size_type k = 0; k < b.size(); ++k)
    //{
    //  cout << b[k] << endl;
    //}
    for (deque<int>::size_type n = 0; n < c.size(); ++n)
    {        cout << c[n] << endl;
    }    vector<int>::iterator first = a.begin(); 
    vector<int>::iterator last = a.end();    while (first != last)
    {        cout << "迭代器循环" << endl;        cout << *first << endl;
        ++first;
    }    vector<int>::const_iterator cfirsta = ca.begin();//const不能push_back 数据


    vector<int>::reverse_iterator rfirsta = a.rbegin();//逆序迭代器
    vector<int>::reverse_iterator rlastra = a.rend();//从最后一个倒着向前


    vector<int>::size_type              a1;    vector<int>::iterator    a2;//迭代器
    vector<int>::const_iterator         a3;//常迭代器
    vector<int>::reverse_iterator       a4;//逆序迭代器，从最后一个元素向前迭代
    vector<int>::const_reverse_iterator a5;//常逆序迭代器
    vector<int>::difference_type        a6;//容器中两个数据之间的距离
    vector<int>::value_type             a7;    //vector<int>::reference  a8;
    //引用，引用必须初始化
    //vector<int>::const_reference        a9;//常引用

    list<int>::size_type         
            b1;    list<int>::iterator       
              b2;    list<int>::const_iterator    
            b3;    list<int>::reverse_iterator   
            b4;    list<int>::const_reverse_iterator  
             b5;    list<int>::difference_type        
             b6;    /*list<int>::reference          
            b7;*/
    //如上，deque同上
    system("pause");   
     return 0;
