STL map

简单代码。随着学习会慢慢改

#include<map>#include<string>#include<iostream>using namespace std;int main(){map <int,string>map_student;map_student.insert(pair<int,string>(1,"student_one"));map_student.insert(map<int,string>::value_type(2,"student_two"));map_student[0] = "student_three";map<int,string>::iterator iter;for(iter = map_student.begin() ;iter != map_student.end();iter++) {cout << iter -> first <<" " <<  iter -> second << endl;}cout << endl;iter = map_student.find(1); if(iter != map_student.end()){cout << iter -> second << endl;}elsecout << "not find" << endl;cout << endl;iter = map_student.find(1);map_student.erase(iter); for(iter = map_student.begin() ;iter != map_student.end();iter++) {cout << iter -> first <<" " <<  iter -> second << endl;}cout << endl;} 

希望有用
