What is the difference between function overriding and overloading?

What is the difference between function overriding and overloading?

Function overriding occurs when a subclass provides a specific implementation of a method that is already defined in its superclass. In contrast, function overloading allows multiple functions to have the same name but different parameters within the same scope.

Can you give me an example of function overriding?

Sure! If you have a class Animal with a method makeSound(), and a subclass Dog that overrides makeSound() to return 'Bark', that's function overriding.

And what about function overloading?

For function overloading, consider a function add(int a, int b) and another add(double a, double b). Both functions are named add but accept different parameter types.

Are there any programming languages that do not support function overloading?

Yes, some languages like Python do not support function overloading in the traditional sense, but you can achieve similar behavior using default arguments or variable-length arguments.
