Define a class list for encapsulation, so that can be operated by a suffix list:
 . 1 #include <list>
 2 #include <Vector>
 . 3 #include <the iostream>
 . 4 #include < String > 
 . 5  
. 6  the using  namespace STD;
 . 7  
. 8  class the Test
 . 9  {
 10  public :
 . 11      the Test ();
 12 is      // ~ the Test (); 
13 is      the Test (List < String > strlist);
 14      String & operator [] ( int n-);It should generally have // & can be prevented (the process as return values, there will be a copy of the value down) to call an object constructor returns
 15  
16  public :
 . 17      List < String > m_strList;
 18 is  };
 . 19  
20 is  
21 is :: the Test the Test (List < String > strlist)
 22 is  {
 23 is      m_strList = strlist;
 24  }
 25  
26 is  // the Test :: ~ the Test ()     // when defining destructor, achieved without error.
 27  // {
 28  // 
29  // } 
30  
31 is  String & the Test :: operator[](int n)
32 {
33     list<string>::iterator i = m_strList.begin();
34     vector<list<string>::iterator> vecStrIter;
35     for (; i != m_strList.end(); i++)
36     {
37         vecStrIter.push_back(i);
38     }
39     return *(vecStrIter[n]);
40 }

43 int main()
44 {
45     string str[4] = {"a", "li", "ba", "ba!"};
46     list<string> strList(str, str+4);
47     Test test(strList);
48     cout << test[1] << endl;
