Scopes and Symbol Tables

Consider the following code:

$1$ int a $=0$;

$2$ int b $=0$;

$3$ void print $()\{$

$4$ printf $("\%$d $,\%$ d $",$ a $,$ b $)$;

$5\}$

$6$

$7$ int fun$1()\{$

$8$ int a $,$ c ;

$9$ a $=1$; b $=2$; c $=3$;

$10$ print $()$

$11$ return c ;

$12\}$

$13$

$14$ void fun$2($ int c $)\{$

$15$ int a ;

$16$ a $=9$; b $=$ c ;

$17$ print $()$;

$18\}$

$19$

$20$ int main $()\{$

$21$ a $=$ fun$1()$;

$22$ fun$2(8)$;

$23$ print $()$;

$24$ return $0$;

$25\}$

$1.$ Draw the symbol tables in separation for all $5$ scopes in this program. Assume each

table contains two columns: name and type.

$2.$ What is the output of the above code with static scoping? Justify your answer by

showing the tree of the symbol tables.

$3.$ What is the output of the above code with dynamic scoping? Justify your answer by

showing the tree of the symbol tables
