C Program To Implement Dictionary Using Hashing Algorithms Here

Here is the C code for the dictionary implementation using hashing algorithms:

// Hash function int hash(char* key) { int hashCode = 0; for (int i = 0; i < strlen(key); i++) { hashCode += key[i]; } return hashCode % HASH_TABLE_SIZE; } c program to implement dictionary using hashing algorithms

In this paper, we implemented a dictionary using hashing algorithms in C programming language. We discussed the design and implementation of the dictionary, including the hash function, insertion, search, and deletion operations. The C code provided demonstrates the implementation of the dictionary using hashing algorithms. This implementation provides efficient insertion, search, and deletion operations, making it suitable for a wide range of applications. Here is the C code for the dictionary

typedef struct Node { char* key; char* value; struct Node* next; } Node; This implementation provides efficient insertion

typedef struct HashTable { Node** buckets; int size; } HashTable;

// Search for a value by its key char* search(HashTable* hashTable, char* key) { int index = hash(key); Node* current = hashTable->buckets[index]; while (current != NULL) { if (strcmp(current->key, key) == 0) { return current->value; } current = current->next; } return NULL; }

// 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; } previous = current; current = current->next; } } }
