map/vector遍历删除

Posted 2020-08-24 风的哀伤

map遍历删除

 

1 map<int, vector<int>>::iterator it = g_map.begin();
2 for (; it != g_map.end(); /*it++*/)
3 {
4     g_map.erase(it++);
5 }

 

vector遍历删除

 1 vector<int>::iterator iter = vec.begin();
 2 while (iter != vec.end())
 3 {
 4     if(*iter == 1)
 5     {
 6     iter = vec.earse(iter);
 7     }
 8     else
 9     {
10         ++iter;     
11     }          
12 }
