Nettet3. aug. 2024 · Defining the Hash Table Data Structures. A hash table is an array of items, which are { key: value } pairs. First, define the item structure: HashTable.cpp. // Defines the HashTable item. typedef struct Ht_item { char* key; char* value; } Ht_item; Now, the hash table has an array of pointers that point to Ht_item, so it is a double-pointer.
