     Question 14 To use mathematical functions like sqrt, you need to #include what file? iostream functions cmath mathfunc none of these Done  
  
  Solution
Header <cmath> declares a set of functions to compute common mathematical operations and transformations:
math.h is a C library header. Its use is deprecated, but allowed in C++.
 
 cmath is a C++ library header. It has the stuff from math.h in the correct namespace plus a lot more .
So the correct option is cmath
