迭代器之map的简单介绍

#include<iostream>

 #include<string>

 #include<map>

 using namespace std;


 //typedef map<int,string> UDT_MAP_INT_STRING;

 //UDT_MAP_INT_STRING enumMap;


 int main()

 {

     cout<<"........"<<endl;

     map<int,string> enumMap; 

     enumMap.insert(pair<int,string>(1,"student_one"));

     enumMap.insert(pair<int,string>(2,"student_two"));

     enumMap.insert(pair<int,string>(3,"student_third"));

     enumMap.insert(pair<int,string>(3,"student_third"));

     enumMap.insert(pair<int,string>(3,"student_third"));

     enumMap.insert(pair<int,string>(3,"student_third"));

     map<int,string>::iterator iter;

     for(iter=enumMap.begin();iter!=enumMap.end();iter++)

     {

         cout<<iter->first<<""<<iter->second;

         cout<<""<<endl;

     

     }

     getchar();

 }
