An interpreter differs from a compiler in that an interpreter

  • A.performs no lexical or syntactic analysis of the given source at all
  • B.can only process programs written in assembly language
  • C.executes the source program directly rather than producing a target
  • D.always produces faster running programs than a compiler does

Answer: C

An interpreter carries out the operations of the source program on the inputs supplied. It still analyses the program, but instead of emitting code it performs the actions, which usually makes execution slower and diagnostics better.
