Operator Overloading

• You can also overload the input operator to read in other types of objects.

  istream & operator>>(istream& in, Time& a)
  {
     int hours;
     int minutes;
     int seconds;
     in >> hours >> minutes >> seconds;
     a = Time(hours, minutes, seconds);
     return in;
  }
  

• Note that the >> operator returns the input stream just like the << operator.
• Unlike the << operator, the >> operator must have a parameter of Time&.
• It is easy to go overboard overloading operators! Using inappropriate operators can make programs more difficult to read.
  • Does it make sense to overload *, / or % for Time objects?
