Problem $2$: Scopes and Symbol Tables

Consider the following code:

int x $=2$;

void $(*$func$\_$ptr$)()$;

bool use$\_$alternate $=$ false;

void g$($int y$)\{$

if $($y$>0)\{$

int x $=$ y $+2$;

g$($y $-1)$;

$\}$ else $\{$

func$\_$ptr$()$;

$\}$

$\}$

void f$()\{$

print$($x$)$;

$\}$

void alt$()\{$

if $(\}$x$==2)$

x $=100$;

$\}$ else $\{$

int x $=7$;

x $+=3$;

$\}$

print$($x$)$;

$\}$

void h$()\{$

int x $=10$;

if $($use$\_$alternate$)\{$

func$\_$ptr $=$ &alt;

$\}$ else $\{$

func$\_$ptr $=$ &f;

$\}$

g$(3)$;

$\}$

h $()$;

$\}$

Draw the symbol tables for all relevant scopes. Include entries for both

variables and function pointers under static scoping.

What is the expected output when the code is executed using static scoping

and dynamic scoping? Trace through the execution of the program and explain how

x is resolved in each function.

Now, suppose use$\_$alternate $=$ true. What would the output be under both

static scoping and dynamic scoping?
