hash_map在vs2005 vs2008中怎么用？

[ayw215]

它里面是的hash table是动态变化的么？
怎么使用它呢？
希望可以给个例子？

使用跟map一样吧

//正好刚刚看到一个！你看看吧！跟map差不多！第一个是key第二个是value
#include <iostream>
#include <hash_map>
#include <string>

using namespace std;

int main()
{
    hash_map<string, string> phonebook;
    string a,b;
    for(int i=0; true; i++)
    {
        cin>>a>>b;
        if(a == "!"||b=="!")
            break;
        phonebook[a] = b;
    }

    hash_map <string,string>::iterator phoneIter;
    for(phoneIter=phonebook.begin(); phoneIter!= phonebook.end(); phoneIter++)
    {
        cout<<phoneIter->first<<"  "<<phoneIter->second<<endl;
    }
    // by key
    cin>>a;
    phoneIter = phonebook.find(a);
    cout<<phoneIter->first<<"  "<<phoneIter->second<<endl;

    // by value
    cin>>b;
    for(phoneIter=phonebook.begin(); phoneIter!= phonebook.end(); phoneIter++)
    {
        if(phoneIter->second == b)
        {
            cout<<phoneIter->first<<"  "<<phoneIter->second<<endl;
            break;
        }
    }
    return 0;
}
