Classes and Objects with friends


Enhance Date function with friend and operator methods


1. Start with the Date class developed previously in class. A copy is here : DateClass

2. Add a friend function "bool Equals(Date a, Date b)" that returns true if the dates are equal

3. Can we do arithmetic with dates?

  • Days between to dates?
  • Add days to date to get new date
  • check if a date is real
  • what about leap year?
Review these algorithms on computing years with leap year: link

Algorithms converted to friend functions: link

Add a friend function "Date Add(Date d, int i) " that adds an integer i days to Date, and returns that date.
Add a operator "==" if the two are equal.
Add a "+" opperator that adds Date with an integer: d2 = d1 + 16;
