dataTypes.swift

import UIKit

var x = 20

let const = 7

var x1 : Int = 13

var x2 : Double = 6.2

var x3 : Float = 3.377777

var sum = x1 + Int(x2)

typealias myNumber = Int

var y : myNumber = 6

print(y)

var doter : Bool = true

(doter == true ? print("Bye!") : print("Hello!"))

var zp = 10_000_000
