Consider the following program written in C syntax

#include $$stdio$.$h$>$

int $a,b,c$;

int $g()$

$\{$

$\}$

return $b$;

int $f($int $x,$ int $y$

$\{$

int $b=3$

$x=g()+b$;

$\}$

return $x$;

void main$()$

$\{$

int $a=1$;

int $b=2$;

int $c=3$;

$b=f(a,c)$;

printf$("\%$d $\%$d $\%$d

$",$ b $)$;

$3$

The output of this program using dynamic scoping is:

$2$

$3$

$4$

$5$
