Question

Which of the following statements is/are true in the context of interpreters?

• $S1$: Interpreters process program according to the logical flow of control through the program.
• $S2$: Interpreter translates and executes the error-free first instruction before it goes to the second.
• $S3$: Interpreter processing time is less compared with compiler.
• $S4$: LISP and Prolog are interpreted languages.

 

• A. Only $S1$
• B. Only $S3$
• C. Only $S1$, $S2$ and $S3$
• D. Only $S1$, $S2$ and $S4$

Comments

I think it is D

Answer 1

S1: Interpreters process program according to the logical flow of control through the program.  TRUE

S2: Interpreters translates and executes the error-free first instruction before it goes to the second. TRUE

S3: Interpreter processing time is less compared with compiler. FALSE

      Because Compiler processing time is FASTER than Interpreter.

S4: LISP and Prolog are interpreted languages. TRUE

 So, option (D) Only S1, S2 and S4 is CORRECT
