Consider the grammar for variable declarations:
D → T L
T → int { T.type = int }
T → float { T.type = float }
L → L1 , id { addType(id.lexeme, L1.inh); L.inh = L1.inh }
L → id { addType(id.lexeme, L.inh) }
Which of the following statements about this SDD is true ?

Question

Consider the grammar for variable declarations:  
 D → T L 
 T → int    { T.type = int } 
 T → float  { T.type = float } 
 L → L1 , id   { addType(id.lexeme, L1.inh); L.inh = L1.inh } 
 L → id        { addType(id.lexeme, L.inh) } 
 Which of the following statements about this SDD is  true ?
