# Zig Programming Cheat Sheet

This guide condenses the key ideas from Chapter 1 of the Zig book, emphasizing Zig's syntax, semantics, workflows, and philosophy. It distills nuanced language details, technical rules, compiler constraints, and examples for direct application by AI or technical users.

## 1. Zig Philosophy and Paradigm

- Zig is a **low-level, general-purpose, modern programming language** designed for safety, control, and simplicity.
- Major design goal: **Less is more** (removes confusing/unsafe C/C++ behaviors; adds consistency).
