What is a protected class C++?
The protected keyword specifies access to class members in the member list until the next access specification (public or private) or the end of the class definition. Class members declared as protected may only be used in member functions of the class that originally declared these members.
What is the difference between public and private modifiers?

Private member variables or functions cannot be accessed, nor can they be accessed from outside the class. Only class and friend functions can access private members.
What is private variable in Python?
In general, private variables are variables that are visible and accessible only within the class to which they belong, not outside the class or other classes. These variables are used to access values whenever a program is executed that is used to keep data hidden from other classes.

What is a public method?
Public methods can be accessed in a private way from anywhere and only from the same class. The main advantage is control over the class API. If you expose only what you need, you can modify the internal behavior of the class without breaking the code according to this class.
What is private computer?
Private is a keyword that specifies the access level and gives the programmer some control over the variables and methods hidden in the class. Variables and methods defined with the private keyword can only be accessed by other methods in the class and not in derived classes.

How do you create an abstract base class in C++?
Create an abstract class by declaring at least one pure virtual member function. This is a virtual function declared using pure specification (= 0) syntax. Classes derived from an abstract class must implement pure virtual functions. Or they are also abstract classes. // deriv_abstractclasses.
Can a child class access private?
Access to inherited private fields. Inheritance means that objects in a child class automatically contain the object fields and methods defined in the parent class. However, if the inherited fields are private, as it should be, the child class cannot directly access the inherited fields using dot notation.
