Which of the following library function below by default aborts the program?

  1. Terminate()

  2. end()

  3. abort()

  4. exit()


Correct Option: A

AI Explanation

To answer this question, you need to understand the purpose and behavior of each library function mentioned.

Option A) Terminate() - This option is incorrect because there is no standard library function called "Terminate()" that aborts the program by default.

Option B) end() - This option is incorrect because there is no standard library function called "end()" that aborts the program by default.

Option C) abort() - This option is correct because the "abort()" function is a standard library function that is used to terminate the program abnormally. When the "abort()" function is called, it causes the program to terminate immediately and generate a core dump (if supported by the operating system).

Option D) exit() - This option is incorrect because the "exit()" function does not abort the program by default. The "exit()" function is used to terminate the program normally by returning an exit status to the operating system.

The correct answer is C) abort(). This option is correct because the "abort()" function is the library function that by default aborts the program.
