18. An alternate term for lexical analyzer is:
a. pattern matcher.
c. pushdown automaton.
d. all of the above.
19. A concept of ________ means that a small number of primitive
constructs can be combined in a small number of ways to build the
control and data structures of the language.
20. The task of a bottom-up parser is to find the handle of any given
right sentential form that can be generated by its associated
