What is the primary function of a compiler?

• A. Executes code
• B. Translates high-level language into machine code
• C. Stores data
• D. Manages memory

Answer: (B)

Translating a high-level language into machine code is what a compiler does. It takes source code written in languages humans write programs in and converts it into instructions that a computer’s processor can execute directly. This process may include syntax and semantic checks, optimization, and producing an executable or object code that can later be linked. The compiler itself doesn’t run the program at runtime, nor is its primary job to store data or manage memory; those are responsibilities of the runtime system and the operating system. That translation step is why this choice is the best answer.
