WebMar 12, 2024 · Hash Table C++. Hash table or a hash map is a data structure that stores pointers to the elements of the original data array. In our library example, the hash table for the library will contain pointers to each of the books in the library. Having entries in the hash table makes it easier to search for a particular element in the array. WebThere are two common styles of hashmap implementation: Separate chaining: one with an array of buckets (linked lists) Open addressing: a single array allocated with extra space so index collisions may be resolved by placing the entry in an adjacent slot.
