HashMap Implementation in C

This project implements a simple hash map in C using separate chaining to handle collisions. It provides basic operations such as creating the map, inserting key-value pairs, removing entries, checking whether a key exists, displaying the contents, and freeing memory.

Features

• Create a hash map
• Insert key-value pairs
• Remove entries by key
• Check whether a key already exists
• Display all stored entries
• Clean up allocated memory

Project Files

• hashMap.c - Contains the hash map implementation
• header.h - Defines the node structure, hash map structure, and function prototypes
• main.c - Demonstrates basic usage of the hash map

Build and Run

Compile the program with:

gcc main.c hashMap.c -o program

Run it with:

./program

On Windows, you can also run the generated executable:

program.exe

Example Behavior

The sample driver inserts a few key-value pairs, displays them, removes some entries, and then clears the memory.
