Topic: Concepts of
Kindly provide a bit detailed answer
4. a) Consider the following program, written in JavaScript-like syntax:
// main program
var x, y, z;
function sub1() {
var a, x, z;
. . . }
function sub2() {
var a, b, y;
. . .}
function sub3() {
var a, y, w;
. . .}
Given the following calling sequences and assuming that dynamic scoping is
used, what variables are visible during execution of the last subprogram
activated? Include with each visible variable the name of the unit where it is
declared.
“main calls sub1; sub1 calls sub3; sub3 calls sub2.”
