There are three different ways to implement polymorphism in C++.

1. Static polymorphism (early binding): achieved using function overloading and operator overloading, the compiler determines the function or operator that will be called at compile time.
2. Dynamic polymorphism (late binding): implemented using virtual functions and pointers/references, the function to be called is determined at runtime based on the actual type of the object.
3. Pure virtual functions and abstract classes: By declaring virtual functions as pure virtual functions and defining the class as an abstract class, the unified definition of interfaces is achieved, and subclasses must implement pure virtual functions in order to be instantiated.
