What is the difference between function overloading and function overriding in C++?

What is the difference between function overloading and function overriding in C++?

Function overloading allows multiple functions with the same name but different parameters, while function overriding redefines a base class method in a derived class.

Can you give me an example of function overloading?

Sure! For instance, you can have a function add(int a, int b) and another add(double a, double b). Both are named add but accept different types.

And what about function overriding?

In function overriding, if you have a base class Animal with a method speak(), a derived class Dog can override speak() to provide a specific implementation.

Are there any rules for function overloading?

Yes, the functions must differ in the type or number of parameters. The return type alone cannot be used to distinguish overloaded functions.
