Using your favorite imperative language, give an example of each of the following. (a) a lexical error, detected by the scanner (b) a syntax error, detected by the parser (c) a static semantic error, detected by semantic analysis (d) a dynamic semantic error, detected by code generated by the compiler (e) an error that the compiler can neither catch nor easily generate code to catch (this should be a violation of the language definition, not just a program bug)
