Swift 4

Question

class MarksStruct {
var mark: Int
init(mark: Int) {
self.mark = mark
}
}

class studentMarks {
var mark = 300
}

let marks = studentMarks()
print("Mark is \(marks.mark)")

why class is declared twice? are we connecting to the first one?

Answer 1

I don't see declare twice of class in your code. You mean 'marks.mark' ? If so, you just use the marks instance of studentMarks class and access its variable 'mark' using dot notation.
Output will be 300.
