在c 11中初始化字符串列表

#include<string>
#include<list>
#include<iostream>
using namespace std;

int main() {
      string s = "Mark";
      list<string> l  {"name of the guy"," is Mark"};
      cout<<s<<endl;
      int size = sizeof(l)/sizeof(l[0]);
      for (int i=0;i<size;i++) {
             cout<<l[i]<<endl;
      }
      return 0;
 }

I / O是

strtest.cpp:8:47: error: in C++98 ‘l’ must be initialized by constructor,not 
 by ‘{...}’
 list<string> l  {"name of the guy"," is Mark"};
