What is an example for ambiguous grammar?

Following are some examples of ambiguous grammar: S-> aS |Sa| Є E-> E +E | E*E| id. A -> AA | (A) | a.

What is ambiguous grammar is the grammar P -> q p q -> ε ambiguous?

A Grammar that makes more than one Leftmost Derivation (or Rightmost Derivation) for the similar sentence is called Ambiguous Grammar.

What is ambiguous grammar problems?

A grammar is said to be ambiguous if there exists more than one leftmost derivation or more than one rightmost derivation or more than one parse tree for the given input string. If the grammar is not ambiguous, then it is called unambiguous. If the grammar has ambiguity, then it is not good for compiler construction.

What is ambiguous question example?

An ambiguous question is defined as one where there is no specific query, it could have more than one meaning, asking for several responses, or not clearly defining the subject/object. Here are some examples with reasons why they aren't good questions: Did you see the film last weekend? – what film?

Is there any technique to remove ambiguity?

One can get rid of the ambiguity by encoding operator precedence and as- sociativity. Let us assume that ∗ binds more strongly than ⊕ and ⊗ and that these bind more strongly than &. We also assume that ⊕ and ⊗ bind equally tight and that ambiguity between these is resolved by choosing left associativity.

How do you correct an ambiguous pronoun?

An ambiguous pronoun occurs when a sentence contains two possible antecedents, leaving the reader or listener unaware of which the pronoun is referring to, also known as a faulty pronoun reference. As a way to avoid ambiguity, it is best to place the pronoun close to its antecedent.

How do you disambiguate an ambiguous sentence?

1. To disambiguate a sentence, you must write at least two sentences that are free of the original ambiguity. 2. Add no new meaning-bearing elements: this is a matter of being charitable to the speaker/writer, even if it means preserving an element or elements of vagueness, which is a separate issue.

How do I know if my CFG is ambiguous?

A CFG is ambiguous if one or more terminal strings have multiple leftmost derivations from the start symbol. Equivalently: multiple rightmost derivations, or multiple parse trees.

What is ambiguous grammar show that following grammar is ambiguous or not a → A A − A * A?

A grammar is said to be ambiguous if there exists more than one left most derivation or more than one right most derivation or more than one parse tree for a given input string. If the grammar is not ambiguous then we call it unambiguous grammar.

What is ambiguous in English grammar?

adjective. If you describe something as ambiguous, you mean that it is unclear or confusing because it can be understood in more than one way. This agreement is very ambiguous and open to various interpretations.

What are the 4 types of ambiguity?

Phonetics, grammar, semantics, syntax, as small as punctuation and intonation can all be the cause of ambiguity. Based on this, linguists divide ambiguity into different types such as phonetic ambiguity, lexical ambiguity, syntactic ambiguity, and pragmatic ambiguity.

Is C++ grammar ambiguous?

If a string has more than one parse tree in a given grammar, that grammar is called ambiguous. C++ uses the parse tree corresponding to (ostream << string) << int , a fact that is dictated by << 's left-to-right associativity.

What is ambiguous grammar MCQ?

A grammar is said to be ambiguous if it can produce more than one parse tree for a string or when two different sequences of leftmost (or rightmost) derivations can produce the same string from the same start symbol.

What is ambiguous language?

Linguistic ambiguity is a quality of language that makes speech or written text open to multiple interpretations. That quality makes the meaning difficult or impossible for a person or artificial intelligence (AI) program to reliably decode without some additional information.
