c++中map容器的使用



#include <map>
#include <cstdlib>
#include <string>
#include <iostream>

using namespace std;
int main(){
map<string,int> word_count;
word_count["Anna"] = 1;
word_count["Lily"] = 2;
word_count["Ryan"] = 1;
word_count.insert(map<string,int>::value_type("havey",3));
map<string,int>::const_iterator map_it = word_count.begin();
while (map_it != word_count.end())
{
cout << map_it->first << "occurs" <<map_it->second << "times" << endl;
++map_it;
}
return 0;
}
