【c++程序】map一般用法

#include<iostream>
using namespace std;
#include<map>
#include"print.h"

template<typename T>
void print(T b,T e,char c=' ')
{
while(b!=e)
cout<<*b++ <<c;
cout<<endl;
}
template<typename K,typename V>
ostream& operator<<(ostream& o, const pair<K,V>& p)
{
return o<<p.first<<':'<<p.second;

}
int main()
{
map<int ,string>mis;
mis.insert(pair<int,string>(1,"Zhao"));
mis.insert(make_pair(4,"Hong"));
mis[3]="Meng";
mis[6]="Zhu";
mis.insert(make_pair(5,"Zhao"));
mis.insert(make_pair(6,"Fang"));
print(mis.begin(),mis.end());
mis[8]="Xiujing";
print(mis.begin(),mis.end());

}
