• High Level Language
• Low Level Language

If the programmer chooses a high‑level language, they can use a compiler or an interpreter to translate the high‑level language into a low‑level language. Select one option that best describes the translator: Checks one line of code(line by line) and then translates/executes it. The program stops when an error is found and only resumes execution after debugging is done.

• Compiler
• Interpreter

If the programmer chooses a high‑level language, they can use a compiler or an interpreter to translate the high‑level language into a low‑level language. Select one option that best describes the translator: Checks all code at once before translating/executing any code. Produces an executable file and error report with all errors for the whole source code.
