📝 Walkthrough

Walkthrough

The array examples in course versions 11, 12, 14, 15, 16, and release now explicitly evaluate their labeled fancy_array initialization blocks at compile time and verify the final element. The documentation adds a Compiler Explorer example link.

Changes

Array initialization examples

Layer / File(s)	Summary
Explicit compile-time array initialization course/code/{11,12,14,15,16}/array.zig, course/code/release/array.zig	The fancy_array initialization blocks now use explicit compile-time evaluation. Each example adds an assertion that fancy_array[9] equals 9.
Compiler Explorer example link course/basic/advanced_type/array.md	The compile-time array initialization documentation now includes a Compiler Explorer link.

Add an assertion for the computed array.

This example contains logic that can be validated with a meaningful assertion. Add a test that checks all ten values are 0 through 9. Do not test only that printing succeeds.

Based on learnings: Zig examples under course/code/16/ should add tests when the example contains logic that can be validated with meaningful assertions.

fancy_array initialized by the init block, asserting that it contains exactly
ten elements with values 0 through 9 in order. Ensure the test validates the
array contents rather than only exercising its printing.

assertions verifying all ten values are 0 through 9; validate the array contents
directly rather than testing printed output.
