C Program To Implement Dictionary Using Hashing Function Examples
In this lab we're making hashtables in C. We've been using C arrays for the past two. String key and then turned the hash code (named hashCode in the PDF) into an index. You'll be implementing the following functions in Dictionary.c. As an example, we need to dereference the pointer to the pointer.

Hash Table is a data structure which stores data in an associative manner. In hash table, the data is stored in an array format where each data value has its own unique index value. Access of data becomes very fast, if we know the index of the desired data.
Implementation in C
If we compile and run the above program, it will produce the following result −
Output
This is the C++ implementation of Dictionary using Hash TablesThe code has been written from scratch by Himanshu Singal.Object Oriented approach is used.The main file is testdictionary.cpp which consists of the guide to use the dictionary_hash.h header.Linear Probing,Double Hashing and Chaining are the collision techniques used.User is free to choose any technique.

testdictionary.cpp is the implementaion file.inventory.h consists of the record class which has to be inserted in dictionary.dictionary_hash.h is the header file for dictionary.openhashing.h is the header file for hashing with collision method linear probing and double hashing.chainhashing.h is for hashing using chaining as collision avoiding technique.hashing.h is for calculating the hash code map and mapping key to an index.primegen.h is for finding the prime number next to a given prime number.linkedlist.h is for the linked list using chaining(templates has been used).linearlist.h is for the seqential list(templates has been used).database.txt is the database file.
