var div: Int { return self / 5 }

}

let addition = 3.add

println("Addition is \(addition)")

let subtraction = 120.sub

println("Subtraction is \(subtraction)")

let multiplication = 39.mul

println("Multiplication is \(multiplication)")

let division = 55.div

println("Division is \(division)")

let mix = 30.add + 34.sub

println("Mixed Type is \(mix)")

When we run the above program using playground, we get the following result:

Addition is 103

Subtraction is 110

Multiplication is 390

Division is 11

Mixed Type is 154

Initializers

Swift provides the flexibility to add new initializers to an existing type by extensions. The
user can add their own custom types to extend the types already defined and additional
initialization options are also possible. Extensions supports only init(). deinit() is not
supported by the extensions.

struct sum {

var num1 = 100 , num2 = 200

}

struct diff {

var no1 = 200 , no2 = 100
