A common misunderstanding is that an interpreter compiles the entire program into object code, similar to a compiler. However, an interpreter processes each instruction individually.
Explanations:
An interpreter translates and executes each instruction of a program one at a time. This means that the interpreter reads the source code, translates it into machine code, and executes it immediately. This process is repeated for each instruction in the program. Therefore, the statement "It translates one instruction at a time" is correct.
Option Analysis:
Option A:
Correct. An interpreter translates and executes one instruction at a time.
Option B:
Incorrect. Object code is not saved for future use in an interpreter; it is executed immediately.
Option C:
Incorrect. Repeated interpretation is necessary because the interpreter processes each instruction individually each time the program is run.
