What else can I help you with?
What is member fusion in c plus plus?
If you are asking about member functions. When we declare a function inside a class then that function becomes member function of that class and this function can access the whole class
Can you access in drive class from base class private data?
Base class should no knowledge about derived classes. The "private" modifier on a data member means private to the class which defined it. Base class cannot directly reference/access the private data member of the derived class, and the derived classes cannot access the private data member defined in the base class. Either way the accessing the private data member should be done via properties or getters
Is the default access specifier same as protected?
A private member of a class can only be accessed by methods of that class. A protected member of a class can only be accessed by methods of that class and by methods of a derived class of that class.
How would you access data members of a class in cases inside member function of another class?
Either make the data members public, or make the member function a friend of the class containing the data member.
Can you access a protected member from a Sub class outside the package of its Base class?
Protected members of a class are only accessible to its subclasses and to friends of the class or its subclasses. However, if a subclass changes the access to private, only the subclass and its friends have access but this does not affect the access rights of its ancestors or their friends.
Can you access a default member from inside a Sub class?
No.

Is it possible to restrict a friend class's access to the private data member?
No. De-friend the friend class and provide an access method function.
What is the difference between friend function and normal member function?
We can access a Friend function from any other class in which friend function is introduced or declared even if the other class is not a member of first class. But when we use normal member function, we can have its access only in the derived classes of the first class. This is the basic difference between a friend function and a normal member function.

Which access limitation is found in a class member declared protected internal?
"Internal" is not a C++ keyword, so it is meaningless in this context. "Protected" means that the class member is visible to (has scope from) only the class and classes derived from the class.
How you declare class scoped variables and member functions?
To scope class members to the class (rather than to instances of the class), declare them as static members of the class. Static members are accessible even when no instances of the class exist. As such, static member functions do not have access to a 'this' pointer, unlike ordinary (nonstatic) member functions.
Difference friend and public access modifier?
In C++, a friend function or friend class can grant access to its private data members to other classes. The public member allows any class to access that data.
Only public member functions can access public member data TrueFalse?
False. Public member data is accessible to all functions, whether they be public, protected or private members of the same class, or they are outside of the class completely.
