Exercise : Polymorphism - General Questions
  • Polymorphism - General Questions
6.
What is operator overloading?
The ability of a function to take different types of arguments
The ability of a class to inherit from multiple classes
The ability of an object to take on multiple forms or types
The ability to define custom behavior for operators in a class
Answer: Option
Explanation:
Operator overloading in Python allows you to define custom behavior for operators in a class by implementing special methods like __add__(), __sub__(), etc.
7.
Which of the following is an example of method overloading?
Defining a method with the same name in a class
Defining a method with the same name but different parameters in a class
Defining a method with the same name but different return types in a class
Defining a method with different access modifiers in a class
Answer: Option
Explanation:
Method overloading in Python is achieved by defining a method with the same name but different parameters in a class.
8.
Consider the following code: 
class Animal:
    def speak(self):
        pass

class Dog(Animal):
    def speak(self):
        return "Woof!"

class Cat(Animal):
    def speak(self):
        return "Meow!"
What concept is demonstrated in this code?
Method overloading
Method overriding
Operator overloading
Polymorphism
Answer: Option
Explanation:
This code demonstrates method overriding, where the subclasses provide specific implementations for a method defined in the superclass.
9.
How is polymorphism different from encapsulation?
Polymorphism is the ability to hide implementation details, while encapsulation is the ability of an object to take on multiple forms.
Polymorphism is the ability to define custom behavior for operators, while encapsulation is the bundling of data and methods that operate on the data.
Polymorphism is the ability of a function to take different types of arguments, while encapsulation is the ability to represent data and the methods that operate on the data within a single unit.
Polymorphism is the ability of an object to take on multiple forms or types, while encapsulation is the ability to restrict access to certain details of an object and only expose what is necessary.
Answer: Option
Explanation:
Polymorphism is about the ability of objects to take on multiple forms or types, while encapsulation is about bundling data and methods within a single unit and controlling access to details.
10.
What is the purpose of the __iter__() method in Python classes in the context of polymorphism?
To create a new instance of the class
To customize the behavior when an instance is deleted
To customize the behavior when the iter() function is called on an instance
To access superclass attributes directly
Answer: Option
Explanation:
The __iter__() method is used to customize the behavior when the iter() function is called on an instance of the class, allowing for polymorphic behavior.
