C Program To Implement Dictionary Using Hashing Algorithms May 2026

The most efficient way to implement a dictionary in C is through . This article will guide you through the complete process of implementing a dictionary from scratch using separate chaining and linear probing, analyze different hash functions, and discuss performance optimizations.

unsigned long hash_djb2(const char *str) unsigned long hash = 5381; int c; while ((c = *str++)) hash = ((hash << 5) + hash) + c; /* hash * 33 + c */ return hash; c program to implement dictionary using hashing algorithms

free(old_buckets); Always free memory to avoid leaks. The most efficient way to implement a dictionary

insert(dict, "name", "Alice Johnson"); insert(dict, "city", "New York"); insert(dict, "occupation", "Software Engineer"); analyze different hash functions
