What is access specifier in C Plus Plus?
The access specifiers used in C++ are Private, Protected and Public. The data members and member functions of a class declared as public are available to everyone and other classes can also access them. The public members of a class are accessible from everywhere in the program using the dot operator (.)
Access Specifiers
By now, you are quite familiar with the public keyword that appears in all of our class examples:
Example
The public keyword is an access specifier. Access specifiers define how the members (attributes and methods) of a class can be accessed. In the example above, the members are public - which means that they can be accessed and modified from outside the code.
Why is the output of the above program a compile time error?
The output of above program is a compile time error because we are not allowed to access the private data members of a class directly outside the class. Yet an access to obj.radius is attempted, radius being a private data member we obtain a compilation error.
What are access modifiers used for?
Access modifiers are used to implement an important aspect of Object-Oriented Programming known as Data Hiding. Consider a real-life example:#N#The Research and analysis wing (R&AW), having 10 core members has come in possession of sensitive confidential information regarding national security. Now we can correlate these core members to data members or member functions of a class which in turn can be correlated to the R&A wing. These 10 members can directly access confidential information from their wing (the class), but anyone apart from these 10 members can’t access this information directly i.e. outside functions other than those prevalent in the class itself can’t access information that is not entitled to them, without having either assigned privileges (such as those possessed by friend class and inherited class as will be seen in this article ahead) or access to one of these 10 members who is allowed direct access to the confidential information (similar to how private members of a class can be accessed in the outside world through public member functions of the class that have direct access to private members). This is what data hiding is in practice.#N#Access Modifiers or Access Specifiers in a class are used to assign the accessibility to the class members. That is, it sets some restrictions on the class members not to get directly accessed by the outside functions.#N#There are 3 types of access modifiers available in C++:
Can a member function be accessed by other classes?
The data members and member functions declared as public can be accessed by other classes and functions too. The public members of a class can be accessed from anywhere in the program using the direct member access operator (.) with the object of that class.
What is protected access modifier?
Protected: Protected access modifier is similar to private access modifier in the sense that it can’t be accessed outside of it’s class unless with the help of friend class, the difference is that the class members declared as Protected can be accessed by any subclass (derived class) of that class as well.
Public Specifier
Public class members and functions can be used from outside of a class by any function or other classes. You can access public data members or function directly by using dot operator (.) or (arrow operator-> with pointers).
Protected Specifier
Protected class members and functions can be used inside its class. Protected members and functions cannot be accessed from other classes directly. Additionally protected access specifier allows friend functions and classes to access these data members and functions.
Private Specifier
Private class members and functions can be used only inside of class and by friend functions and classes.
