Theory of Computation (Automata)
What is Halting problem primarily used for?
Difficulty: Hard
About this MCQ
This Hard Theory of Computation (Automata) question asks: What is Halting problem primarily used for? The correct choice is C. The undecidable problem of determining whether a given program will finish running or continue forever.. 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, non-empty set of symbols used to construct strings in a formal language.
Why not A: “A finite, non-empty set of symbols used to construct strings in a formal language.” does not fit this question. The answer is The undecidable problem of determining whether a given program will finish running or continue forever..
- B. A visual representation showing how an automaton moves between states based on input symbols.
Why not B: “A visual representation showing how an automaton moves between states based on input symbols.” does not fit this question. The answer is The undecidable problem of determining whether a given program will finish running or continue forever..
- C. The undecidable problem of determining whether a given program will finish running or continue forever. ✓
- 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 The undecidable problem of determining whether a given program will finish running or continue forever..
Correct answer
C. The undecidable problem of determining whether a given program will finish running or continue forever.
Explanation
The undecidable problem of determining whether a given program will finish running or continue forever is the value that answers What is Halting problem primarily used for option C Option A A finite non-empty set of symbols used to construct strings in a formal language does not fit this question Option B A visual representation showing how an automaton moves between states based on input symbols does not fit this question Option D An abstract machine with a finite number of states used to recognize patterns in input strings does not fit this question For this Theory of Computation Automata question the accepted answer is The undecidable problem of determining.
