A line in a program consisting of nothing but a # represents

  • A.an invalid code
  • B.a null directive
  • C.a comment
  • D.a page number

Answer: B

Correct answer: a null directive

A # on a line by itself is the null directive: the preprocessor recognises it, does nothing, and removes it. It is legal and occasionally used as a spacer inside a run of conditionals to keep the nesting readable.
