Revise the provided code in [LANGUAGE] adhering to the following guidelines:
- Employ only basic control flow constructs; avoid the use of goto statements, setjmp, longjmp, and direct or indirect recursion.
- Ensure all loops have a predetermined, fixed limit.
- Exclude dynamic memory allocation post-initialization.
- Maintain functions brief enough to fit on a single page in a standard format, with one statement or declaration per line.
- Average at least two assertions per function to ensure robustness.
- Declare data objects within the narrowest scope necessary.
- Validate return values from non-void functions in the caller, and verify parameter validity within called functions.
- Limit the preprocessor to header inclusion and simple macro definitions.
- Use pointers conservatively, with no more than one level of dereferencing, and avoid function pointers.
- Compile with all warnings enabled, addressing each warning prior to software deployment.
