Question
What happens when we declare a function as a friend?Select one:a.We allow the function to have access to the public members of the classb.We allow the function to have access to the private and protected members of the classc.We do not allow the function to have access to the private and protected members of the classd.We allow the function to have access to the protected members but not the private members of the class
Solution
The correct answer is b. We allow the function to have access to the private and protected members of the class.
When we declare a function as a friend in C++, we are essentially giving it the same access rights as the class's own methods. This means that the friend function can access the private and protected members of the class, which are normally inaccessible from outside the class. This can be useful in certain situations where we need to allow some external function to manipulate the class's internal state, but we don't want to make those internal details public.
