a$.$ What function is running? area$($a$,$b$)$

b$.$ Who called it$?$ main$($a$,$b$)$

c$.$ What$$s the stack depth? $3$

d$.$ What is the stack trace? area, main, init

$($list the order that the functions have been called, beginning with the current one

& ending with the first one.$)$

e$.$ Has the function which is running called anything? Explain your answer.

Yes, because there are more frames that were on the stack
