Code Complete, 2nd Edition

Key Points

• Multiple returns can enhance a routine's readability and maintainability, and they help prevent deeply nested logic. They should, nevertheless, be used carefully.

• Recursion provides elegant solutions to a small set of problems. Use it carefully, too.

• In a few cases, gotos are the best way to write code that's readable and maintainable. Such cases are rare. Use gotos only as a last resort.
