Using the C++ program below answer the questions that follow.

1 int a = 0; //global variables

2 int b = 0;

3 int getVal(int c)

4 {

5 int n = 0;

6 a = c;

7 if (n < c)

8 n = a + b;

9 return n;

10 }

11 int newVal(int c)

12 {

13 int n = 0;

14 { int a = c;

15 if (n < getVal(c))

16 n = a + b; 17 }

18 return n;

19 }

20 void main ( )

21 {

22 int j = 1; 23 int b = newVal(j);

24 cout << a + b + j << endl; 25 return 0; 26 } ------------------------------------------

a) Show the stack of activation records that would exist When line 8 has executed, but before line 9

executes.

b) Which variables are alive at this point? c) Show the stack again after the execution of line 24, but before the execution of line 25.

d) Which variables are alive now?

The stack should look like this: https://imgur.com/a/Yt12zhJ
