WebA parsing action is called accept when the start symbol is present in the stack and the input buffer is empty therefore which means successful parsing. The parser will announces successful completion of parsing. Error. Whereby the parser can not perform shift, reduce or accept actions due to a syntax error. An error recovery routine is called. WebThis way, the parser accomplishes two tasks, i.e., parsing the code, looking for errors and generating a parse tree as the output of the phase. Parsers are expected to parse the whole code even if some errors exist in the program. Parsers use error recovering strategies, which we will learn later in this chapter. Derivation

WebThe following are the error-recovery actions in lexical analysis: 1) Deleting an extraneous character. 2) Inserting a missing character. 3)Replacing an incorrect character by a correct character. 4)Transforming two adjacent characters. 5) Panic mode recovery: Deletion of successive characters from the token until error is resolved.
