LL (1) grammars are suitable for handwritten parsers at best, because
every rule of the parser then can be considered as a specification for
the creation of a routine in your programming language.
The C parser at
nearly is an LL(1) adaption from the yacc grammar:
To read the grammar, you will have to install the free version of
There are two places, where a look-ahead was necessary. E.g. in the
The second look-ahead is in the rule "parameter_declaration". At this
