Which library function converts a string to a double-precision floating point value ?

  • A.atoi()
  • B.atol()
  • C.atof()
  • D.strtok()

Answer: C

Correct answer: atof()

atof() parses a string into a double, atoi() into an int and atol() into a long. strtok() is unrelated, splitting a string into tokens on a set of delimiters.
