counter.incrementBy(no1: 100 , no2: 5 )

counter.incrementBy(no1: 15000 , no2: 3 )

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

500

45000

Self property in Methods

Methods have an implicit property known as 'self' for all its defined type instances. 'Self'
property is used to refer the current instances for its defined methods.

class calculations {

let a: Int

let b: Int

let res: Int

init(a: Int, b: Int) {

self.a = a

self.b = b

res = a + b

println("Inside Self Block: \(res)")

}

func tot(c: Int) - > Int {

return res - c

}

func result() {

println("Result is: \(tot(20))")

println("Result is: \(tot(50))")

}

}

let pri = calculations(a: 600 , b: 300 )

let sum = calculations(a: 1200 , b: 300 )
