Zig Config Reader Exercise: Environment Variables, Defaults, and Validation

A practical two-hour session on Zig Config Reader Exercise, focused on Environment Variables, Defaults, and Validation. Zig is used realistically for systems tooling, C interop, parsing, build workflows, and performance-minded components rather than pretending it is a full web platform.

Audience: entry-level and intermediate developers who want a practical engineering session, not a language tour.

Outcomes:

• Explain the practical boundaries of Zig Config Reader Exercise
• Apply Environment Variables in a small working example
• Apply Defaults in a small working example
• Apply and Validation in a small working example

Format: two hours with a short framing walkthrough, a concrete example, discussion of tradeoffs, and a closing checklist for practice.
