C String Hash Map

A small, educational hash map implementation in C with string keys and generic pointer values (void*).
Collisions are handled with separate chaining (linked lists per bucket). Includes a tiny demo.c harness for quick builds.

This repo contains only code and documentation written by me (no course handouts/prompts or instructor-provided tests).

What it does

• Create a map with a configurable number of buckets
• Insert or replace a key/value pair
• Lookup a value by key
• Remove a key/value pair (returns the stored value pointer)
• Debug-print bucket contents (dump())

Project layout

• src/strmap.c — implementation
• src/strmap.h — public header (opaque strmap_t)
• demo.c — simple demo program

Build & run (Windows + GCC / MSYS2)
