Which is private member functions access scope?
A. Member functions which can used outside the class
B. Member functions which can only be used within the class
C. Member functions which are accessible in derived class
D. Member functions which can’t be accessed inside the class
A. Member functions which can used outside the class
B. Member functions which can only be used within the class
C. Member functions which are accessible in derived class
D. Member functions which can’t be accessed inside the class
Private member functions can only be used within the class, meaning their access scope is within the class.
