They contain machine code and can be run directly by the OS/loader, D. They always require an IDE to run, Why might a programmer choose assembly language or machine code over a high-level language?, A. Because they are simpler to write, B. To avoid using registers, C. To get precise, direct control of hardware or optimise for speed/size, D. Because they allow auto-suggestion, Which statement about interpreters is FALSE?, A. They execute instructions as they are translated, B. They are useful for debugging during development, C. They produce an executable file to distribute, D.
