Given the following program:

$1$ int h$,$ i;

$2$ void B$($int w$)\{$

$3$ int j$,$ k;

$4$ i $=2*$ w;

$5$ w $=$ w $+1$;

$6...$

$7\}$

$8$ void A$($int x$,$ int y$)\{$

$9$ float i$,$ j;

$10$ B$($h$)$;

$11$ i $=3$;

$12...$

$13\}$

$14$ void main$()\{$

$15$ int a$,$ b;

$16$ h $=5$; a $=3$; b $=2$;

$17$ A$($a$,$ b$)$;

$18$ B$($h$)$;

$19...$

$20\}$

a$.$ Assume dynamic scoping and a call history of: main$($line $17)->$ A$($line $10)->$ B$.$ For each function

list all of the variables referenced and the line on which it was declared
