3. Context-free languages are useful for the definition of programming languages. For example, we have looked at grammars for defining Lisp and C. (a) Give a context-free language that is not regular, establishing the added power of CFL (b) What language is accepted by the following grammar: (c) Build a context-free grammar for the language (wb w-wR, k 0 a,by (d) Build a context-free grammar for the language of nested parentheses. A left parenthesis should always precede its matching right parenthesis. Two strings in this language are () and (00)0. This grammar could be used to check the syntactic correctness of a Lisp expression. Show transcribed image text 3. Context-free languages are useful for the definition of programming languages.
