Time.cpp

/*Create a class 'Time' with hours, minutes and seconds as private data members,
  two constructors (one default and one parameterized), 
  two public methods increment_min() and print().
  Also write a private function convertToSec() that converts and returns the stored time into seconds?.
  Show the use of such an object through the main() function.
