please I want the solution for all this multiple choice , in C++ language

Question 2)

When class B is inherited from class A, what is the order in which the destructor of those classes are executed

2. Which of the following cannot be overloaded?

A. member functions

B. constructors

C. destructors

D. BandC

3. The default access level assigned to members of a class is ___________

A. Private

B. Public

C. Protected

D. Needs to be assigned

4. For which type of class private and protected members of the class can be accessed from outside the same class in which they are declared

A. No such class exist

B. Friend

C. Static

D. Virtual

5. Which of the following is not allowed

A. SomeClass[] f1() { . . . }

B. SomeClass * f1() { . . . }

C. SomeClass f1() { . . . }

D. SomeClass f1(int h) { . . . }

6. Given the following class:

class Example {

public: int a,b,c;

};

int main() {

Example * obj1 = new Example(1);

Example * obj2 = new Example(1,3);

Example * obj3 = new Example(1,6,7);

return 0;

}
