Dictionary Using Hashing Algorithms — C Program To Implement

: Using Separate Chaining allows the dictionary to store more elements than the table size, though performance drops as the "load factor" increases. 5. Practical Use Example

Run the dictionary with 100,000 insertions and measure average time per operation using clock() or gettimeofday() .

// Delete a key-value pair from the hash table void delete(HashTable* hashTable, char* key) int index = hash(key); Node* current = hashTable->buckets[index]; if (current == NULL) return; if (strcmp(current->key, key) == 0) hashTable->buckets[index] = current->next; free(current->key); free(current->value); free(current); else Node* previous = current; current = current->next; while (current != NULL) if (strcmp(current->key, key) == 0) previous->next = current->next; free(current->key); free(current->value); free(current); return; c program to implement dictionary using hashing algorithms

current = current->next;

. If the hash function is poor and many keys collide in one bucket, it can degrade to (linked list traversal). : Using Separate Chaining allows the dictionary to

In C, the dictionary structure typically consists of:

bool ht_contains(HashTable *ht, const char *key) return ht_get(ht, key, NULL); // Delete a key-value pair from the hash

Before diving into the code, it is important to understand the three pillars of a hash-based dictionary:
