OOPs

In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.

Constructor

The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

Question

12:45
o legs that will initialize to 0
o
boolean swim that will initialize to
false;
• All classes will have the following
polymorphic methods, including Animal
o getLegs() - this returns the number
of legs the animal has
o makeSound() - this outputs the
type of sound the animal makes
o canSwim()- this will return true or
●
false
makeSound() method will be a virtual
function in the Animal class
• Create an exception in the getLegs()
●
method that makes sure the number of
legs are valid
• Create a main method to demonstrate the
●
all functions including the following with
appropriate output
Animal animal;
animal.makeSound();
Gorilla gorilla
gorilla.makeSound();
cout << gorilla.getLegs();
Animal badGorilla = Gorilla();
badGorilla.makeSound();
.5G
cout << badGorilla.getLegs();
Fish fish;
fish.makeSount();
Bird bird;
bird.makeSourd();
bird.getLegs(); //2

Each class has different requirements, read them carefully. Do not use the exec or eval functions, nor are you allowed to use regular expressions (re module). All methods that output a string must return the string, not print it. If you are unable to complete a method, use the pass statement to avoid syntax errors.
