Choose the correct answer to the question. Which of these is not a property of a class? Member variables and member functions may be public, protected, or private. A class may not use another class as the type for a member variable. The name of a member function for a class may be overloaded just like the name of an ordinary function. A function may have formal parameters whose types are classes. A function may return an object of a class. Choose the correct answer to the question.The copy constructor is executed... When one object is assigned to another object at its creation When objects are passed to a function using call by value When the function returns an object reference.b, c only a, b onlyAll of the abovearrow_forward
