WebIn formal language theory, a context-free language ( CFL) is a language generated by a context-free grammar (CFG). Context-free languages have many applications in programming languages, in particular, most arithmetic expressions are generated by context-free grammars. Background [ edit] Context-free grammar [ edit] WebClosure Properties Basic idea Closure Properties Summary CFLs are closed under Union, Concatenation, Kleene Star CFLs are NOT closed under Intersection, Difference, Complement But The intersection of a CFL with a RL is a CFL Decision Properties Questions we can ask about context free languages and how we answer such questions.
