Theory of Computation (Automata)
Choose the correct description of Regular expression.
Difficulty: Medium
About this MCQ
This Medium Theory of Computation (Automata) question asks: Choose the correct description of Regular expression. The correct choice is C. A sequence of characters that defines a search pattern, corresponding to regular languages.. Read the options below, commit to one, then use the explanation to see why that choice holds and why the others do not.
Theory of Computation (Automata) items like this one are written for Pakistan exams such as CSS, FPSC, PPSC, and NTS. The difficulty label is a hint about how much of the topic the stem assumes, not a score. Tags and exam names, when they are present, tell you where else the same idea is tested. Previous and next links stay in Theory of Computation (Automata) so you can continue the subject. Related questions point at nearby stems if you want another angle on the same idea.
Treat the explanation as part of the question, not a footnote. If you missed it, reread the stem against the correct option before you open the next Theory of Computation (Automata) item. A timed quiz is the same pool with a clock and a score. A past paper is a full sitting rather than this single question.
- A. A finite automaton that may have multiple possible transitions for a given state and input symbol.
Why not A: “A finite automaton that may have multiple possible transitions for a given state and input symbol.” does not fit this question. The answer is A sequence of characters that defines a search pattern, corresponding to regular languages..
- B. A language that can be expressed using a regular expression or recognized by a finite automaton.
Why not B: “A language that can be expressed using a regular expression or recognized by a finite automaton.” does not fit this question. The answer is A sequence of characters that defines a search pattern, corresponding to regular languages..
- C. A sequence of characters that defines a search pattern, corresponding to regular languages. ✓
- D. An abstract machine with a finite number of states used to recognize patterns in input strings.
Why not D: “An abstract machine with a finite number of states used to recognize patterns in input strings.” does not fit this question. The answer is A sequence of characters that defines a search pattern, corresponding to regular languages..
Correct answer
C. A sequence of characters that defines a search pattern, corresponding to regular languages.
