A member function can always access the data in:
Multiple Choice Options
- A
The object of which it is a member
- B
The class of which it is member
- C✓ Correct Option
Any object of the class of which it is a member
- D
The public part of its class
Detailed Technical Solution & Explanation
In C++, access control (private, protected, public) is enforced at the class level, not the individual object level. Therefore, a member function can access private and protected data of *any* object that belongs to the same class (for example, in a copy constructor or assignment operator where this->data = other.data;).
Option Analysis:
•
Option A (The object of which it is a member): While it can access its own object, access control is per-class, so this is incomplete.
•
Option B (The class of which it is member): Data belongs to class instances, but between instances of the same class, access is unrestricted.
•
Option C (Any object of the class of which it i...): Correct. Member functions have complete access to private, protected, and public members of any instance of their class.
•
Option D (The public part of its class): A member function has access to all parts (private, protected, public), not just the public part.
