Which of the following is defined under the header file time.h?

  • A.strncat()
  • B.fabs()
  • C.iscntrl()
  • D.NULL

Answer: D

Correct answer: NULL

NULL is one of the few names defined in several headers at once, <time.h> among them - so a program gets it from whichever it happens to include. fabs belongs to <math.h>, iscntrl to <ctype.h> and the string functions to <string.h>.
