Context-free languages

A context-free language is a type of formal language in computer science characterized by its ability to be generated by a set of rules called a context-free grammar. These rules specify how to form valid strings or sequences—such as balanced parentheses or nested structures—without depending on the surrounding symbols. This concept helps in designing programming languages and understanding how compilers parse code. Essentially, context-free languages are a broad class of languages that can be described with simple rules, making them fundamental for analyzing syntax in software development and computational theory.
