C Program To Implement Dictionary Using Hashing Algorithms Direct

Building a Dictionary in C Using Hashing Algorithms

Introduction

In computer science, a dictionary (also known as a map, associative array, or symbol table) is a data structure that stores key-value pairs. It provides efficient insertion, deletion, and lookup operations. When implementing a dictionary in C—a language without built-in associative arrays—hashing algorithms offer the most practical and performant solution.

#include <pthread.h>
destroy_table(dict);
    return 0;
Advantages:
#define INITIAL_SIZE 16
#define LOAD_FACTOR_THRESHOLD 0.75 c program to implement dictionary using hashing algorithms
Delete a key
int delete_key(Dictionary* dict, const char* key) 
    int index = hash(key, dict->size);
    Entry* curr = dict->buckets[index];
    Entry* prev = NULL;
while (curr != NULL) 
    if (strcmp(curr->key, key) == 0) 
        if (prev == NULL) 
            // deleting head of chain
            dict->buckets[index] = curr->next;
         else 
            prev->next = curr->next;
