Overview of Compiler Phases
Compilers are crucial in translating high-level programming languages into machine code. They comprise several phases, each serving a specific purpose. The phases include:
What is Syntax Analysis?
Syntax Analysis, often referred to as parsing, is the second phase of the compiler. Its main responsibility is to check if the sequence of tokens generated during lexical analysis adheres to the grammatical rules of the programming language.
Importance of Syntax Analysis
Syntax analysis is vital because it ensures that the program follows the correct structure defined by the language's grammar. Without this phase, the compiler cannot proceed to semantic analysis or optimization, as it relies on syntactically correct code.
In conclusion, the correct answer to the question is option 'A', as Syntax Analysis is indeed the second phase of the compiler.

- Code Generation
What is Syntax Analysis?
Syntax Analysis, often referred to as parsing, is the second phase of the compiler. Its main responsibility is to check if the sequence of tokens generated during lexical analysis adheres to the grammatical rules of the programming language.
- Input: The output from the lexical analysis phase, which consists of tokens.
- Process: Syntax analysis constructs a parse tree or abstract syntax tree (AST) based on the grammar rules.
- Output: A syntactically correct representation of the program, or an error message if the syntax is incorrect.
Importance of Syntax Analysis
Syntax analysis is vital because it ensures that the program follows the correct structure defined by the language's grammar. Without this phase, the compiler cannot proceed to semantic analysis or optimization, as it relies on syntactically correct code.
- Error Detection: It identifies issues related to incorrect syntax, such as missing brackets or misplaced keywords.
- Structure Creation: It lays the foundation for further analysis by creating a parse tree.
In conclusion, the correct answer to the question is option 'A', as Syntax Analysis is indeed the second phase of the compiler.
