The value of an element in a hash_map, but not its associated key value, may be changed directly. Instead, key values associated with old elements must be deleted and new key values associated with new elements inserted. Use hash_map? ? Hashed associative containers are optimized for the operations of lookup, insertion and removal. ? Hash_multimap ? hash_set ? hash_multiset 定義、插入、遍
