STL之map模板(映射)

#include<iostream>
#include<map> 
using namespace std;
int main(){
    
    
	map<string,int>	mp;
	mp["hi"]=5;
	string x="every";
	int y=100;
	mp[x]=y;
	if(mp.count("word"))
		;//是否存在word?
	mp.erase("hi"); 
	mp.size();
	for(map<string,int>::iterator it=mp.begin();
		it!=mp.end();it++){
    
    
		string k=it->first;
		int v=it->second;
		cout<<k<<" "<<v<<endl;
	} 
	return 0;
}
