Question

Scala code

To explanation from start

Consider the following Scala code: def foo(a : Int) { var b = a + 3 def bar(g : Int) { val h b + g } def jat(...) { bar(...) } val w jat (...) Functions bar and jat are nested inside function foo. Function bar relies on foo's local variable b. Assuming a Scala implementation using stack frames, explain how variable b is located at runtime when it is referenced in bar when foo calls jat which calls bar. Include a sketch of the stack frames to illustrate your answer.
