1. Consider the following SDT for type declarations: PMDM{offset=0;}DTid;{top.put(id.lexeme,T.type,offset);offset=offset+T.width;}DTrecord}{Env.push(top);top=newEnv();Stack.push(offset);offset=0;}D}{T.type=record(top);T.width=offset;top=Env.pop();offset=Stack.pop();}TB{t=B.type;w=B.width;}Bint{T.type=C.type;T.width=C.width}Bfloat{B.type=float;B.width=8;}C{C.type=t;C.width=w;}C[num]C1{C.type=array(num.value,C1.type);C.width=num.valueC1.width;} Fig 1: SDT for type declaration a. Determine the types and relative addresses for the identifiers in the following declaration by drawing the annotated parse tree and evaluating the attribute values of each non- terminal of the SDT: record { float [2][3]a; int b;}p
