What term describes programming languages that are executed line-by-line at runtime?

• A. Interpreted
• B. Scripting languages
• C. Markup languages
• D. AI-generated code

Answer: (A)

Interpreted describes languages that are executed by an interpreter at runtime, translating and executing instructions on the fly rather than producing a standalone executable beforehand. The interpreter reads the source code and processes it line by line or in small chunks, which often makes development quicker and cross-platform, but can be slower during execution due to the ongoing interpretation. This differs from compiled languages, which are transformed into machine code ahead of time and run directly on the hardware. Markup languages aren’t executed as programs, and AI-generated code isn’t a language category. So the term that best fits languages that run line-by-line at runtime is interpreted.
