Access Specifiers in C++

With C++, you can specify the level of access to member data and functions. There are three levels of access: public, protected, and private.

Access Specifiers:

Public : Available to everyone

Private : Class members declared as private can be used only by member functions and friends (classes or functions) of the class.
If someone tries to access a private member, they’ll get a compile-time error.

Protected : Class members declared as protected can be used by member functions and friends (classes or functions) of the class. Additionally, they can be used by classes derived from the class.
