c++ - how to fetch and assign a list of strings which are values of map -


below mentioned map, stored list of string based on string key.

 std::map<std::string, std::list<std::string>>mapheadertofields;     list<string> strlist;

now return list, , assign return list newly created list variable. how can that?

i tried achieve using below mentioned code snippet. but,i couldn't able assign list. suggestions on how approach on problem. 

for (iteheadertofield = mapheadertofields.begin(); iteheadertofield != mapheadertofields.end(); iteheadertofield++)     {         cout << "key :" << iteheadertofield->first<<endl;         strlist.assign((iteheadertofield->second.begin(),(iteheadertofield->second.end());         ((_mapheadertofields.find((iteheadertofield)->first)));     }

i tried fetch second element map , assigned list.but, couldn't able assign list. compiler throwing error when assigned list.

is there other way can make it?

you can use std::list's copy assignment operator

strlist = iteheadertofield->second;

this copy list pointed iterator second element strlist.
