What does a Syntactic Analyser do?
Creating Parse Tree:
A syntactic analyzer, also known as a parser, is responsible for analyzing the syntax of a programming language. One of the main tasks of a syntactic analyzer is to create a parse tree, which represents the syntactic structure of the input program. The parse tree is used to check whether the input program conforms to the grammar rules of the programming language.
Understanding Syntax:
The syntactic analyzer checks the input program for syntax errors and ensures that it follows the rules defined by the grammar of the programming language. It identifies the relationships between different parts of the program and determines the correct order of operations.
Error Detection:
In addition to creating the parse tree, the syntactic analyzer also detects and reports syntax errors in the input program. This helps programmers identify and correct mistakes in their code before running it.
Identifying Language Constructs:
The syntactic analyzer identifies various language constructs such as statements, expressions, variables, functions, and control structures in the input program. By understanding the syntax of the program, it lays the foundation for further analysis and processing.
In conclusion, a syntactic analyzer plays a crucial role in the compilation process by analyzing the syntax of a programming language, creating a parse tree, detecting syntax errors, and identifying language constructs.
