map/vector遍历删除

map遍历删除

 map<int, vector<int>>::iterator it = g_map.begin();
 for (; it != g_map.end(); /*it++*/)
 {
     g_map.erase(it++);
 }

vector遍历删除

 vector<int>::iterator iter = vec.begin();
 while (iter != vec.end())
 {
     if(*iter == )
     {
     iter = vec.earse(iter);
     }
     else
     {
         ++iter;
     }
 }
