|

## Description
|
||||
Inspired by the [book](https://github.com/drh/cii), and others, this is my
|
||||
personal C codebase. I wanted to improve my C and DSA knowledge, and make some
|
||||
useful tools since C doesn't have many language features. This is meant to be
|
||||
opinionated, and not necessarily modular. It's not meant to be the best way,
|
||||
but I hope to improve it overtime.

||||
