What are the two types of documentation?

• A. Comments and README files
• B. Source code and binaries
• C. Log files and error reports
• D. Design diagrams and prototypes

Answer: (A)

Two common types of documentation in software projects are inline comments and README files. Inline comments explain what specific parts of the code do, the reasoning behind non-obvious decisions, and any tricky logic, right where the code lives so future readers don’t have to deduce it from the code alone. README files provide a high-level overview of the project, how to install and run it, basic usage, dependencies, and guidelines for contributing. These two forms together cover both the micro-level explanations near the code and the macro-level guidance that helps users and contributors get started. Other options aren’t primarily documentation: source code and binaries are the actual program and its compiled form, not explanations or usage guidance; log files and error reports describe what happened during execution rather than how to use or understand the project; design diagrams and prototypes are design artifacts that show planned structure, not the ongoing, practical documentation used for maintenance and onboarding.
