16.允许重复的multimap

#include <iostream>
#include <map>
#include <cstring>
using namespace std;


void main()
{
    multimap<char *, int>mymap;
    mymap.insert(pair<char *, int>("司令1", 10));
    mymap.insert(pair<char *, int>("司令1", 11));
    mymap.insert(pair<char *, int>("司令3", 12));
    mymap.insert(pair<char *, int>("司令4", 13));
    mymap.insert(pair<char *, int>("司令5", 14));

    

    for (auto i : mymap)
    {
        cout << i.first << " " << i.second << endl;
    }

    auto it = mymap.equal_range("司令1");
    for (auto ib = it.first, ie = it.second; ib != ie; ib++)
    {
        cout << (*ib).first << "  " << (*ib).second << endl;
    }
    cin.get();
}
