WitrynaGenerally you create an array called "buckets" that contain the key and value, with an optional pointer to create a linked list. When you access the hash table with a key, you process the key with a custom hash function which will return an integer. You then take the modulus of the result and that is the location of your array index or "bucket". Witryna23 maj 2024 · Generally, hash functions in C are implemented with the unsigned integer types.
