Which category of languages is transformed into machine code before execution?

• A. Interpreted languages
• B. Scripting languages
• C. Assembly languages
• D. Compiled programming languages

Answer: (D)

This question is about how source code is transformed into something the computer can run directly. In compiled languages, a compiler analyzes the whole program and translates it into machine code ahead of time, producing a standalone executable that the processor can execute without needing the original source or a translator at runtime. That upfront translation is what lets the program run directly as fast as possible and without an interpreter present during execution. Interpreted or scripting languages, on the other hand, are typically executed by an interpreter at runtime, translating code on the fly as the program runs, which is different from pre-generating machine code. Assembly language is another case: it’s translated into machine code by an assembler, but it’s considered a very low-level category; the common distinction for high-level languages used in exams is that compiled languages are those transformed into machine code before execution.
