GATE 2024 compiler design Rank Booster Quiz 18

Identify the SDT which follow L-attributed definition but not S-attributed definition.

Consider the following SDT:

What is the missing translation (1) and (2), if the string “2 × 3 + 5 × 3 + 1 × 3” produces 160 instead of 24?

Consider the following SDT :

E → E + T {E.val = E.val - T.val , Printf(E.val)}

E → T {E.val = T.val+1}

T → T*F {T.val = T.val + F.val}

T → F {T.val = 2*F.val}

F → id {F.val = id}

What will be printed when the provided input is : 3*4*5+7 _________.

Convert the following expression from infix to postfix: A/B^C-D ?

Which of the following statements are true regarding syntax directed translations (SDT)?

Consider the following SDT:

S -> (S) {S.x = S₁.x=1}

S -> [S] {S.x = S₁.x}

S -> ε {S.x = 0}

Find the translation of above SDT.
