One can demonstrate that a language is regular by showing that it can be described by a regular grammar or a finite state machine. This means that the language can be generated by a set of rules that are simple and predictable, allowing for easy recognition and manipulation of the language's patterns.
The language defined by the regular expression "add" is not a regular language because it requires counting the number of occurrences of the letter "d," which cannot be done using a finite automaton, a key characteristic of regular languages.
The Pumping Lemma is a tool used in theoretical computer science to prove that a language is not regular. It works by showing that for any regular language, there exists a "pumping length" such that any string longer than that length can be divided into parts that can be repeated to create new strings not in the original language. If this property cannot be demonstrated for a given language, then the language is not regular.
One can demonstrate that a language is context-free by showing that it can be generated by a context-free grammar, which consists of rules that define how the language's sentences can be constructed without needing to consider the surrounding context.
A language is decidable if there exists an algorithm that can determine whether any given input belongs to the language or not. To demonstrate that a language is decidable, one must show that there is a Turing machine or a computer program that can correctly decide whether any input string is in the language or not, within a finite amount of time.
One can demonstrate that a grammar is unambiguous by showing that each sentence in the language has only one possible parse tree, meaning there is only one way to interpret the sentence's structure.

it is not regular language .it is high level language

No, it is not necessarily true that if language A is regular and language B reduces to A, then language B is also regular.
The complement of a regular language is regular because regular languages are closed under complementation. This means that if a language is regular, its complement is also regular.
The complement of a regular language is the set of all strings that are not in the original language. In terms of regular expressions, the complement of a regular language can be represented by negating the regular expression that defines the original language.
The reverse of a regular language is regular because for every string in the original language, there exists a corresponding string in the reversed language that is also regular. This is because regular languages are closed under the operation of reversal, meaning that if a language is regular, its reverse will also be regular.
Yes, a regular language can be infinite.
No, sigma star is not a regular language.
