A category of programming languages that are executed line-by-line at runtime is called?

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

Answer: (C)

Interpreted languages are executed line-by-line at runtime by an interpreter. The interpreter reads each line of code and runs it directly, translating on the fly rather than producing a separate machine-code file beforehand. This on-the-fly execution is what defines the category and explains why programs in these languages are typically run without a distinct compilation step. Scripting languages are often interpreted, but the precise concept here is the execution model—interpreted languages execute code as the program runs. Markup languages aren’t programming languages at all, and AI-generated code isn’t a language category. Examples like Python and JavaScript illustrate languages that are commonly interpreted.
