What is a private member function?

A function declared inside the class’s private section is known as “private member function”. A private member function is accessible through the only public member function. (Read more: data members and member functions in C++).

What is the difference between protected and private access specifiers?

Access specifiers define how the members (attributes and methods) of a class can be accessed. private – members cannot be accessed (or viewed) from outside the class. protected – members cannot be accessed from outside the class, however, they can be accessed in inherited classes.

What is the difference between private public protected?

First and important difference is the accessibility i.e. anything public is accessible to anywhere , anything private is only accessible in the class they are declared , anything protected is accessible outside the package but only to child classes and default is accessible only inside the package.

What is the difference between public/private and protected inheritance?

public inheritance makes public members of the base class public in the derived class, and the protected members of the base class remain protected in the derived class. private inheritance makes the public and protected members of the base class private in the derived class.

What is the difference between private and public function?

What is the difference between public and private members of classes?

Public members of a class A are accessible for all and everyone. Protected members of a class A are not accessible outside of A’s code, but is accessible from the code of any class derived from A. Private members of a class A are not accessible outside of A’s code, or from the code of any class derived from A.

Private members can only be accessed by the class they’re declared in, and by code in the same module. Of course friend functions throw this out the window, but oh well. private members are only accessible from within the class, protected members are accessible in the class and derived classes.

How to access private members of a class in Java?

Accessing Private Members: The private members of a class are not accessible outside the class not even with the object name. However, they can be accessed indirectly through the public member functions of that class.

Should I use private or public member variables?

It is recommended to use private as a default (just like C++ class ses do) to reduce coupling. Protected member variables are most always a bad idea, protected member functions can be used for e.g. the Template Method pattern. Protected members can only be accessed by descendants of the class, and by code in the same module.
