How DFA is used in compiler?
Lexical analysis: DFAs are used in compilers to perform lexical analysis, which involves breaking down a source code into a sequence of tokens.
The DFA is used to recognize the regular expressions that define the tokens, such as keywords, identifiers, numbers, and symbols..
How is automata used in compiler design?
Generally, Finite Automata are required to implement regular expressions.
Being the first phase of the compiler, its job is to read one character at a time from the source program and to generate Lexemes.
The process of forming the words based on pattern rules and converting them into tokens is called Lexeme.Jan 9, 2022.
Which automata used in compiler design?
Finite automata is a state machine that takes a string of symbols as input and changes its state accordingly.
Finite automata is a recognizer for regular expressions.
When a regular expression string is fed into finite automata, it changes its state for each literal..
Which phase of compiler uses finite automata?
Deterministic Finite Automata (DFA).
Non-Deterministic Finite Automata (NFA or NDFA).
Non-Deterministic Finite Automata with epsilon moves (e-NFA or e-NDFA)..

The DFA is used to recognize the regular expressions that define the tokens, such as keywords, identifiers, numbers, and symbols..
Why DFA is used in compiler design?
Automata are widely used for modelling and verification of software, distributed systems, real-time systems, or structured data.
They have been equipped with features to model time and probabilities as well..

- Automata are mathematical models of computation that can be used to solve problems in AI.
Automata can be used to represent and solve problems in a variety of ways, including as finite state machines, pushdown automata, and Turing machines.
