Why inherit function is not called?
Inherit is not a function. It is a class derivation where some of the methods and attributes of the new class inherit from a parent class.
Need of friend function in c plus plus?
Declaring a function to be a friend of a class allows the friend function to gain private (and protected) access to that class, just as it would if it were declared a static member function of the class. Most of the time you will want to use static functions rather than friend functions, but sometimes it is necessary for a member method of another class or an external function to be permitted private access. Although some will tell you this undermines the encapsulation of the class, it does not. If anything, it reinforces that encapsulation, by only allowing the specified function to gain private access. Although the friend function is not physically a member of the class, it automatically becomes tightly bound to the class. That is not necessarily a bad thing when you're only dealing with a limited number of friends, but a class that has many friends can often be an indication of poor class design. Thus it is important to limit friendship and to only use it when it is absolutely required, whenever possible. By way of an example, suppose you have designed a parent and child class. Even without friend functions, the two are implicitly bound to each other: the parent object is a container for child objects, while child objects refer to their parents. All work is delegated and coordinated between the two classes accordingly; they work together as one. Most of the work can be encapsulated without the need to explicitly bind the classes together, however child objects typically refer to their parent object (via a member pointer) and might also be permitted to change their parent, but we wouldn't want to expose that pointer outside of the class, nor would we want to expose any mutators such as child::set_parent() outside of the class. But since the two classes are imlicitly bound to each other, we can declare specific methods of the parent class to be friends of the child class, such as parent::add_child(). In this way we can be sure that whenever we add a child to a parent, the parent not only attaches the child to itself, but also detaches the child from any existing parent beforehand. Far from undermining the encapsulation, this friendship reinforces it, assuring us that both classes are tightly bound.
Why Java always provides a default constructor to class when you use another constructor default constructor remove?
Classes in Java inherit constructors from their parent classes. If you don't explicitly define a parent class, then Object is used, which has only the default empty constructor. That "default" constructor is only there when defined by the parent class, so classes which do not have a no-argument constructor will not allow subclasses to automatically use it. This is implemented this way because of the special nature of constructors. Java could not always provide a default constructor because it could not guarantee that all class members would be properly created or initialized.
In java why method defined in super class need not to defined in subclass?
In Java, or in any object oriented language such as C++, a method defined in super (parent) class does not need to be defined in a subclass, because that is the primary purpose of inheritance. Object oriented programming allows you to define and declare a class that implements the behavior for an object. Inheritance allows you to refine, or subclass, that class by "reusing" all of the functionality of the parent class into the sub class, adding additional definition and declaration for the sub class. If the subclass needs to change a parent class method, it can overload that method. This is called abstraction.
Can a parent class access the functions of child class?
no, Parent class can not access the members of child class ,but child class can access members of parent class

What is the definition of parent function?
When a function is nested inside another function, the outer one is the parent, the inner is the child.
Can a parent function access values of a child function?
In C programming, there aren't any parent or child functions.

parent
The equation y-x is a parent linear function. Its parent function is...?
if you need to reflect a 2-d object on a graph over its parent linear function then do as follows: (x,y) --> (-y,-x) hope that helps
