Please help me with the following assignment!!

$1.$ Convert the folllowing function into $3$AC

int g;

int a$($int b$,$ int c$)\{$

if $($b$)\{$

return $0$;

$\}$ else $\{$

b $=$ b$-1*$c;

$\}$

return b;

$\}$

$2.$ Convert the following function into $3$AC$.$

int v$($int a$)\{$

while $($a$<2)\{$

while $($a$<3)\{$

a$++$;

$\}$

a$++$;

$\}$

return a;

$\}$

$3.$ Convert the following procedure into A$.$ Assume variables are local unless otherwise specified.

enter k

getarg $1,[$b$]$

$[$i$]=[$b$]$

lbl$\_1$: $[$t$]=[$i$]$ LT$6410$

ifz $[$v$]$ goto lbl$\_2$

$[$i$]=[$i$]$ ADD$641$

WRITE $[$i$]$

goto lbl$\_1$

lbl$\_2$: nop

leave k

$4.$ Assume a language that allows for pass$-$by$-$reference or pass$-$by$-$value parameters. What would the $3$AC code look like for a pass$-$by$-$reference call? Illustrate with an example.
