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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3bd0e46b-857f-4ec5-8dd5-f1ba366c71d7%2Fdbabf321-dfaf-4b58-ab63-9e5c5b486a0e%2F44abuas_processed.jpeg&w=3840&q=75)
