Question 51 Explanation:
Statement (I): “The friend function and the member functions of a friend class directly access the private and protected data.”
This statement is generally correct. In C++, a friend function and the member functions of a friend class can directly access the private and protected data of the class they are friends with.
Statement (II): “The friend function can access the private data through the member functions of the base class.”
This statement is incorrect. A friend function can access the private members of the class it is declared as a friend of, but it does not have automatic access to the private members of the base class. Access to the base class’s private members is subject to the base class’s own access rules.
