Visibility
The visibility of a property or method can be defined by prefixing the declaration with the keywords public, protected or private. Class members declared public can be accessed everywhere. Members declared protected can be accessed only within the class itself and by inherited and parent classes. Members declared as private may only be accessed by the class that defines the member.
The policy is if you are not a member, you can’t get it. But there is a certain situation wherein you need to share your private or protected data with nonmembers. ‘Friends’ come here as a rescue.
A friend function is a non-member function that grants access to class’s private and protected members.
