STL map+vector+struct的使用示例

个人编写的小例子，没有注释，刚毕业时作为技术调研随手编写，仅供参考：

#include<iostream>
#include<map>
#include<vector>

using namespace std;

struct date_s
{
        long id;
        string obj_type;
        string obj_name;
};
typedef vector<date_s> S_vector;
int main(int argc,char ** argv)
{
        int table_no;
        vector<date_s> v_data;
        map<int,S_vector> m;
        map<int,S_vector>::iterator it_m;

        date_s d1,d2,d3;
        d1.id = 1;
        d1.obj_name = "lijin";
        d1.obj_type = "man";

        d2.id = 2;
        d2.obj_name = "duanxiang";
        d2.obj_type = "man";

        d3.id = 3;
        d3.obj_name = "yuandong";
        d3.obj_type = "man";

        v_data.push_back(d1);
        v_data.push_back(d2);
        v_data.push_back(d3);
        m[1] = v_data;
        S_vector tmp;

        it_m = m.begin();
        tmp = it_m->second;

        cout<<it_m->second.front().id<<endl;

        for(;it_m != m.end();it_m++)
        {
        // cout<<it_m->first<<":"<<it_m->second.id<<" "<<it_m->second.obj_name<<endl;

        }

        return 0;
}
