Representation of DFA

A DFA (Deterministic Finite Automaton) can be represented in different formats such as transition graph, transition table, and C code.

Transition Graph

- A transition graph is a visual representation of a DFA.
- It consists of a set of nodes (or vertices) representing states and directed edges representing transitions between states.
- Each edge is labeled with an input symbol that triggers the transition from one state to another.
- The initial state is indicated by an arrow pointing to it, and the final (or accepting) states are indicated with double circles.

Transition Table

- A transition table is a tabular representation of a DFA.
- It consists of a set of rows representing states and a set of columns representing input symbols.
- Each cell in the table contains the next state that the DFA will transition to when it receives the input symbol corresponding to the column.
- The initial state is indicated by a row highlighted in some way, and the final states are indicated by a column containing an accept symbol.

C Code

- A DFA can also be represented using C code.
- The code consists of a set of variables representing the states, an input variable representing the current input symbol, and a set of if-else statements that determine the next state based on the current state and input symbol.
- The initial state is assigned to a variable, and the final states are checked at the end of the code to determine if the input string is accepted or rejected.

None of the mentioned

- The statement "A DFA cannot be represented in the following format" is incorrect.
- A DFA can be represented in all the formats mentioned above.
- Therefore, the correct answer is "None of the mentioned."
