WebMar 12, 2024 · We can implement hashing by using arrays or linked lists to program the hash tables. In C++ we also have a feature called “hash map” which is a structure similar to a hash table but each entry is a key-value pair. In C++ its called hash map or simply a map. Hash map in C++ is usually unordered.
