如何显示地图内容？ [英] How to display map contents?

问题描述

我有一张地图

  map< string， string> > mapex;列表< string> li; 
  

如何在控制台上显示上述地图项目。

<$ p $

p> typedef map< string，list< string>> :: const_iterator MapIterator;
for（MapIterator iter = mapex.begin（）; iter！= mapex.end（）; iter ++）
{
cout< Key：<< iter-> first<< endl<< Values：< endl;
typedef list< string> :: const_iterator ListIterator;
for（ListIterator list_iter = iter-> second.begin（）; list_iter！= iter-> second.end（）; list_iter ++）
cout< < * list_iter<< endl;
}


I have a map

 map < string , list < string > > mapex ; list< string > li;

how to display the above map items on the console.

解决方案

Well it depends on how you want to display them, but you can always iterate them easily:

typedef map<string, list<string>>::const_iterator MapIterator;
for (MapIterator iter = mapex.begin(); iter != mapex.end(); iter++)
{
    cout << "Key: " << iter->first << endl << "Values:" << endl;
    typedef list<string>::const_iterator ListIterator;
    for (ListIterator list_iter = iter->second.begin(); list_iter != iter->second.end(); list_iter++)
        cout << " " << *list_iter << endl;
}
