c++list容器的构造

#include "iostream"
#include "vector"
#include "list"
using namespace std;

int main()
{
    //1)创建一个空的list容器。
    list<int> l1;
    //cout<<"l1.capacity()="<<l1.capacity()<<endl;//链表没有容器说法、
    cout<<"li.size()="<<l1.size()<<endl;

    //(2)使用统一列表创建list容器。
    list<int>l2({1,2,3,4,5,6,7,8,9,10});
    for(int value :l2)//用基于的for循环遍历容器。
        cout<<value<<" ";
    cout<<endl;

    //(3)list(const list<T>& v)//拷贝函数、
    list<int>l3(l2);
    for (int value:l3)
        cout<<value<<" ";
    cout<<endl;

    //4)lis(lterator fisrt,lterator last);
    list<int>l4(l3.begin(),l3.end());//用list
    for (int value:l4)
        cout<<"value"<<" ";
    cout<<endl;

    vector<int>v1={1,2,3,4,5,6,7,8,9,10};
    list<int>l5(v1.begin()+2,v1.end()-3);
    for (int value:l5)
        cout<<value<<" ";
    cout<<endl;

    int a1[]={1,2,3,4,5,6,7,8,9,10};
    list<int>l6(a1+2,a1+10-3);
    for (int value:l6)
        cout<<value<<" ";
    cout<<endl;

    char str[]="hello world";
    string s1(str+1,str+7);
    for (auto value:s1)
        cout<<value<<" ";
    cout<<endl;
    cout<<s1<<endl;

    vector<int>v2(l3.begin(),l3.end());
    for (auto value:v2)
        cout<<value<<" ";
    cout<<endl;

}

输出：

li.size()=0
1 2 3 4 5 6 7 8 9 10
1 2 3 4 5 6 7 8 9 10
value value value value value value value value value value
3 4 5 6 7
3 4 5 6 7
e l l o w
ello w
1 2 3 4 5 6 7 8 9 10
