GATE CSE 2017 Set 2 | Question: 05

Question

Match the following according to input (from the left column) to the compiler phase (in the right column) that processes it:
$$\begin{array}{|l|l|}\hline \text{P. Syntax tree}  &  \text{i. Code generator} \\\hline  \text{Q. Character stream} & \text{ii. Syntax analyser} \\\hline  \text{R. Intermediate representation} & \text{iii. Semantic analyser} \\\hline  \text{S. Token stream} & \text{iv. Lexical analyser} \\\hline \end{array}$$

• A. $\text{P-ii; Q-iii; R-iv; S-i}$
• B. $\text{P-ii; Q-i; R-iii; S-iv}$
• C. $\text{P-iii; Q-iv; R-i; S-ii}$
• D. $\text{P-i; Q-iv; R-ii; S-iii}$

Answer 1

C. P-iii; Q-iv; R-i; S-ii;

because Syntax tree come from Syntax analyzer process by Semantic analyzer

             Character stream is input to Lexical analyzer

              Intermediate representation is input to Code generator

              token stream come from Lexical analyzer is input to Syntax analyzer

Comments

C is the ans.
