Match the following according to input (from the left column) to the compiler phase (in the right column) that processes it:

The inputs to the compiler phases are matched as follows:

1. (Q) Character stream is the input to the (iv) Lexical analyzer, which converts characters into a stream of tokens.

2. (S) Token stream is the input to the (ii) Syntax analyzer (parser), which constructs a parse/syntax tree.

3. (P) Syntax tree is the input to the (iii) Semantic analyzer, which performs semantic checks and type checking.

4. (R) Intermediate representation is the input to the (i) Code generator, which translates the intermediate representation into target machine code.

Therefore, the correct mapping is:

• $\text{P} \rightarrow \text{(iii)}$

• $\text{Q} \rightarrow \text{(iv)}$

• $\text{R} \rightarrow \text{(i)}$

• $\text{S} \rightarrow \text{(ii)}$

This corresponds to option (C).
