An operator grammar is which doesn't allow epsilon and two variables side by side in its productions. Operator grammar only can generate a very small class of languages hence, this parse is not used. It's not possible that each language can have an operator precedence grammar corresponding to it. 2 votes 2 votes hacker16 commented Jan 4, 2018 reply Follow Share exactly !! 0 votes 0 votes priyanka manwani commented Jan 10, 2019 reply Follow Share ""Any ambiguous grammar can be parsed by operator precedence parser"" is this statement only true when the grammer is operator precedence or it is always true??? 0 votes 0 votes Please log in or register to add a comment.
