I need an answer to the following basic question:
What kind of language Lex and Yacc implement with regard to Chomsky'
classification? I fond some confusione on the argoment!
Which is the the exact definition of the term LALR and de differences
between LALR and LL?
reply at email@example.com if u can, regards, Davide
[LALR and LL are both subsets of context-free languages, although I
forget the name that linguists use for that. See any compiler text
for the definitions of the two. LALR is a superset of LL. lex just
does regular expressions which I suppose are a particularly simple
kind of CFG. -John]
