Can a parsing table be constructed(with action and goto )practically using some parser

Answer 1

There are many parsers out there for what you are asking for.The one that has feature to parse them online is at this link . this parser has many options available. This is the practical implementation where you need to pass the grammar and it wil generate the parsing tables for you. Not sure about the action and goto .

Yacc is also the one you can have look at. Here is the link . Hope this helped you..
