Question

Consider the following translation schema

S->TR

R->+T{printf(“+);}R|ε

T->num{printf(‘’num.val”);

for the string “9+5+2” the translation schema will print?

A.) 9+5+2

B.) 95+2+

C.) 952++

D.) ++952

My doubt here is: Since it is L-attributed SDT the answer should be 9+5+2 but answer given is 95+2+?

@Ravi kumar singh No they may give different result depending on the grammer.

I am not asking for results I am asking for terms of evaulation

@Ravi kumar singh in s-attributed we calculate in Bottom-up manner, while in l-attributed we evaluate in depth-left to right order.
