To answer this question, you need to understand how member functions of a class are defined.

Option A) :: (Scope resolution operator) - This option is correct because it allows you to define the member functions of a class outside the class. The scope resolution operator is used to define functions outside the class scope.

Option B) ? (Ternary conditional operator) - This option is incorrect because the ternary conditional operator is used for conditional expressions and does not have any relation to defining member functions outside the class.

Option C) :? - This option is incorrect because it does not represent a valid operator in C++.

Option D) % (Modulus operator) - This option is incorrect because the modulus operator is used for calculating the remainder of a division operation and does not have any relation to defining member functions outside the class.

The correct answer is A) :: (Scope resolution operator). This option is correct because it allows you to define the member functions of a class outside the class scope.

To answer this question, you need to understand the concept of constructor functions in object-oriented programming.

In object-oriented programming, a constructor function is a special method that is used to initialize objects of a class. It is called automatically when an object is created from the class.

In many programming languages, including Java and C++, if a class does not explicitly define a constructor function, a default constructor is automatically provided by the compiler. This default constructor initializes the object with default values or performs any necessary setup for the object.

Therefore, even when a constructor function is not explicitly declared in a class, a default constructor is still present. So, the statement "Every class has at least one constructor function, even when none is declared" is true.

Option A) True - This option is correct because, as explained above, every class has at least one constructor function, even if none is explicitly declared. Option B) False - This option is incorrect because, as explained above, even when no constructor function is declared, a default constructor is still present.

The correct answer is A) True. This option is correct because every class has at least one constructor function, even when none is declared.

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.
