c++ maps使用

#include <iostream>
#include <stdio.h>
#include <memory.h>
#include <queue>
#include    <map>

using namespace std;
int main()
{
    //freopen("d://1.text", "r", stdin);
    map<int, string> *maps = new map<int,string>();
    maps->insert(pair<int, string>(, ""));
    maps->insert(pair<int, string>(, ""));
    maps->insert(pair<int, string>(, ""));
    maps->insert(pair<int, string>(, ""));
    maps->insert(pair<int, string>(, ""));
    maps->insert(pair<int, string>(, ""));
    map<int, string>::iterator it;
    for(it = maps->begin(); it != maps->end(); it++)
    {
        cout << "int=" << it->first << " string=" << it->second << endl;
    }
    return ;
}
