  • Context-Free Grammar in Computational Theory

    Context-free grammar (CFG) is a formal system used in computational theory to define the syntax of programming languages, natural languages, and other formal languages. It provides a set of production rules that describe how strings in a language can be generated. CFG is fundamental to parsing and language recognition, forming the backbone of compilers, interpreters,…

  • Compiler Design: Syntax Analysis

    Syntax analysis, or parsing, is the second stage in the compiler design pipeline, following lexical analysis. It validates the structural integrity of source code by ensuring it adheres to the grammatical rules of the programming language. Parsing transforms a sequence of tokens into a hierarchical structure called a parse tree or syntax tree, which serves…
