Back to Basics: Manage Collections with a Custom Dictionary

n Part 1 of this series, I showed you an elementary vector implementation for Brew as a stand-alone component you can use in your applications. This time, I give you a dictionary with a similar interface you can use in your Brew applications. You can download both the vector and hash here.

Introducing the Dictionary
The dictionary, also known as the associative array or hash, is a data structure that provides an interface for storing key-value associations. Typically, the name is a string, and the value may be anything, although in languages like C, you're hard-pressed to store multiple data types in a single dictionary unless you use unions with a type identifier so you know the type of a specific entry.
