What are access modifiers in C++?
Data hiding is one of the important features of Object Oriented Programming which allows preventing the functions of a program to access directly the internal representation of a class type. The access restriction to the class members is specified by the labeled access modifiers: public, private, and protected sections within the class body.
The default access for members and classes is private
class Base {
public:
// public members go here
protected:
// protected members go here
private:
// private members go here
};A public member is accessible from anywhere outside the class but within a program. You can set and get the value of public variables without any member.
A private member variable or function cannot be accessed, or even viewed from outside the class. Only the class and friend functions can access private members.
A protected member variable or function is very similar to a private member but it provided one additional benefit that they can be accessed in child classes which are called derived classes.
