Q43

Consider the following two syntax-directed definitions $\text{SDD1}$ and $\text{SDD2}$ for type declarations. SDD1 Grammar (G1)Semantic Rules D \rightarrow T\ V$$D.type = T.type $V.type = T.type$ T \rightarrow \text{int}$$T.type = \text{int} T \rightarrow \text{float}$$T.type = \text{float} V \rightarrow V_1\ \text{id}$$V_1.type = V.type $\text{put(id.entry, V.type)}$ V \rightarrow \text{id}$$\text{put(id.entry, V.type)} SDD2 Grammar (G2)Semantic Rules D \rightarrow D_1\ \text{id}$$D.type = D_1.type \text{put(id.entry, D_1.type)} D \rightarrow T\ \text{id}$$D.type = T.type $\text{put(id.entry, T.type)}$ T \rightarrow \text{int}$$T.type = \text{int} T \rightarrow \text{float}$$T.type = \text{float} $D$ is the start symbol, and int, float and id are the three terminals. The non-terminal $V_{1}$ is the same as $V$ and the non-terminal $D_{1}$ is the same as $D$. Here, the subscript is used to differentiate the grammar symbols on the two sides of a production. The function put updates the symbol table with the type information for an identifier. Let $\text{P}$ and $\text{Q}$ be the languages specified by grammars $\text{G1}$ and $\text{G2}$, respectively. Which of the following statements is/are true?
