What is your understanding of polymorphism?

Question

OOP

I noticed an interesting point, how people explain what "Polymorphism" is. If everything is more or less the same with the rest of the OOP terms, then when explaining polymorphism, you rarely meet two people who would say the same thing in their own words (terms from the wiki do not count :)). I would like to hear your few words about what "Polymorphism" is after all.

Answer 1

This is a mechanism that allows you to refer to different entities by the same name.
On the example of functions (polyformism by parameters):

int max( int, int );
double max( double, double);

On the example of classes (polyformism by types):

class Animal{}
class Dog : public Animal {}
class Cat : public Animal {}
Animal* animal1 = new Dog();
Animal* animal2 = new Cat();
