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：
1 #include<iostream> 2 #include<map> 3 #include<vector> 4 5 using namespace std; 6 7 struct date_s 8 { 9 long id; 10 string obj_type; 11 string obj_name; 12 }; 13 typedef vector<date_s> S_vector; 14 int main(int argc,char ** argv) 15 { 16 int table_no; 17 vector<date_s> v_data; 18 map<int,S_vector> m; 19 map<int,S_vector>::iterator it_m; 20 21 date_s d1,d2,d3; 22 d1.id = 1; 23 d1.obj_name = "lijin"; 24 d1.obj_type = "man"; 25 26 d2.id = 2; 27 d2.obj_name = "duanxiang"; 28 d2.obj_type = "man"; 29 30 d3.id = 3; 31 d3.obj_name = "yuandong"; 32 d3.obj_type = "man"; 33 34 v_data.push_back(d1); 35 v_data.push_back(d2); 36 v_data.push_back(d3); 37 m[1] = v_data; 38 S_vector tmp; 39 40 it_m = m.begin(); 41 tmp = it_m->second; 42 43 cout<<it_m->second.front().id<<endl; 44 45 for(;it_m != m.end();it_m++) 46 { 47 // cout<<it_m->first<<":"<<it_m->second.id<<" "<<it_m->second.obj_name<<endl; 48 49 } 50 51 return 0; 52 }
