Exercises

• Design a struct named Real whose member properties may only be of type Int or Bool.
• Define initializers:
  • init(_ d:Double)
  • init(_ n:Int)
• Define functions for addition, subtraction, multiplication, and division.
  • All such functions should take the form: func operationName(_ other:Real) -> Real
  • These functions should be named add, subtract, multiply, and divide
