yacc

Yacc (Yet Another Compiler Compiler) is a software tool used in programming to help create programs that understand and process specific languages or commands. It automates the construction of parsers—components that analyze and interpret sequences of symbols or code. By defining grammatical rules, Yacc generates code that recognizes valid patterns and structures within a language, enabling developers to build compilers, interpreters, or other tools that work with complex language syntax efficiently and accurately.
