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 == 1)
    {
    iter = vec.earse(iter);
    }
    else
    {
        ++iter;     
    }          
}
