What is the difference between function overloading and function overriding in object-oriented programming?

Function Overloading vs Function Overriding in Object-Oriented Programming

Function overloading and function overriding are key concepts in object-oriented programming that allow developers to achieve different functionalities within a class. While both techniques involve the use of multiple functions with the same name, they serve distinct purposes.

Function Overloading:

Function overloading is the ability to define multiple functions within a class with the same name but different parameters. This allows developers to create multiple functions that perform similar tasks but with different input parameters. The compiler determines which function to call based on the number and types of parameters passed during the function call.

Function Overriding:

Function overriding, on the other hand, is a concept in inheritance where a subclass provides a specific implementation of a method that is already defined in its superclass. This allows the subclass to provide its own implementation of the method, which overrides the implementation in the superclass. When an object of the subclass is created and the overridden method is called, the subclass's implementation is executed instead of the superclass's.

In summary, function overloading is about defining multiple functions with the same name but different parameters within a class, while function overriding is about providing a specific implementation of a method in a subclass that overrides the implementation in its superclass.
