What does it mean to override a method of the base class?

What does it mean to override a method of the base class?

override (C# reference) An override method provides a new implementation of the method inherited from a base class. The method that is overridden by an override declaration is known as the overridden base method. An override method must have the same signature as the overridden base method.

What do you mean by overriding inheritance?

The ability of a subclass to override a method allows a class to inherit from a superclass whose behavior is “close enough” and then to modify behavior as needed. The overriding method has the same name, number and type of parameters, and return type as the method that it overrides.

How do you override a base class method in Python?

In Python method overriding occurs by simply defining in the child class a method with the same name of a method in the parent class. When you define a method in the object you make this latter able to satisfy that method call, so the implementations of its ancestors do not come in play.

Why do we use overriding?

Method Overriding is a feature that allows us to redefine the method in the subclass or derived class which is already defined in its parent class or superclass. In any object-oriented programming language, we can implement Method Overriding only when two classes have ‘Is-a’ relationship of inheritance between them.

Why do we need method overriding?

The benefit of overriding is: ability to define a behavior that’s specific to the subclass type, which means a subclass can implement a parent class method based on its requirement. In object-oriented terms, overriding means to override the functionality of an existing method.

What is method overriding and how is it useful?

Method overriding, in object-oriented programming, is a language feature that allows a subclass or child class to provide a specific implementation of a method that is already provided by one of its superclasses or parent classes.

When to use method overriding in C + +?

Method Overriding in C++ If we inherit a class into the derived class and provide a definition for one of the base class’s function again inside the derived class, then that function is said to be overridden , and this mechanism is called Function Overriding

Can a method be overridden in a derived class?

Method overriding is possible only in derived classes. Because a method is overridden in the derived class from base class. A method must be a non-virtual or static method for override. Both the override method and the virtual method must have the same access level modifier.

How to access the overridden function of a base class?

To access the overridden function of the base class, we use the scope resolution operator ::. We can also access the overridden function by using a pointer of the base class to point to an object of the derived class and then calling the function from that pointer. accesses the print () function of the Base class.

How is overriding used in the parent class?

Overriding enables handling different data types through a uniform interface. Hence, a generic method could be defined in the parent class, while each child class provides its specific implementation for this method. The invoked method version is determined by the class object.
