C 語言新語法 (C11 之後的改變)

static_assert is a C11 feature that performs compile-time checks to validate constant expressions. It improves code safety by halting compilation immediately when specific assertions fail, preventing potential runtime errors before deployment.

Anonymous structures and unions in C allow convenient data grouping by embedding members directly without a named identifier. You access nested members directly, streamlining syntax and improving readability when managing complex data layouts.

Yes, generic selection expressions enable type-based code branching in C. They evaluate a controlling expression's type and select a corresponding expression, allowing developers to write macros that adapt behavior based on variable data types.

The _Bool data type in modern C programming is a native boolean type introduced for stricter type safety. It stores only the values 0 and 1, ensuring explicit boolean logic and improving code robustness.

To update legacy C code, integrate modern syntax like _Bool, static_assert, and generic selections incrementally. This migration improves type safety, enforces compile-time checks, and enhances overall code expressiveness without breaking existing logic.
