}

let vin = Student(name: "Vin", major: "Info Sci", age: 20)
vin.major // Prints "Info Sci"

    // Inherits properties from the superclass, but you can
    // define other properties specific to this class

    // Initializer
    init(name: String, major: String, age: Int, doesShower: Bool) {
        self.doesShower = doesShower // Initialize properties specific to this class
        super.init(name: name, major: major, age: age) // Call superclass' initializer
    }
}

let archit = EngineeringStudent(name: "Archit", major: "CS", age: 20, doesShower: false)
archit.name // Good
archit.doesShower // Good
vin.doesShower // Does not work
