WitrynaPredictive Parsing Predictive Parsing Just as with lexical analysis, we can either hard-code a top-down parser, or build a generic table-driven interpreter . The latter is called a Predictive Parser . Instead of using recursion we store the current state of the parse on a stack: INTERPRETER Errors Z X $ Y Input: a + b $ Parsing table Stack ...
