Why is the answer 2 1 1 ?

Question

Which choice is the output value of the following code:
var a = 0
let b = ++a
let c = a++
print("\(a) \(b) \(c)")

Why does \(a) = 2 ?

Answer 1

Because it has been incremented twice (first time with ++a, second time with a++). a++ doesn't mean that the incrementation isn't done, just that the value of a is used before the incrementation.
