Model answer
What a good answer should say
- It translates and executes source code during program execution, typically statement by statement
Explanation
Why this works
An interpreter translates and executes a high-level program during execution, commonly one statement at a time. Translating the entire source program before execution describes a compiler, while translating assembly language describes an assembler.
