Answer: C
The correct option is C.
Explanation:
- Lexical Analysis (Scanner): This is the first phase of a compiler. Its primary task is to read the input characters of the source program, group them into lexemes, and produce a sequence of tokens. Keywords (such as
if,else,while,int) are predefined lexemes recognized as specific tokens during this phase. - Parsing (Syntax Analysis): This phase takes the tokens produced by the lexical analyzer and groups them into a hierarchical structure (typically a parse tree) to verify grammatical correctness.
- Code Generation: This is a late phase of the compiler that translates the intermediate representation of the source program into target machine code.
- Dataflow Analysis: This is a technique used during code optimization to gather information about the flow of values along execution paths.
Therefore, keywords of a language are recognized during the lexical analysis of the program.
