Consider the following grammar for the do$-$while statement:

$do-$while$-stmt-dostmt$ while $(exp)$

exp $-$ term relop term

term $-id|$ num

a$)$ Write an attribute grammar for generating three$-$address code for the above CFG grammar

b$)$ Give the sequence of three$-$address code instructions corresponding to the following fragment according to the

attribute grammar you have defined in $($a$)$:

do

s$1/*$ do not generate code fro $s1*\frac{*}{?}$

while $(a>4)$
