OOPs concepts are fundamental to software engineering. They include inheritance, polymorphism, encapsulation, and abstraction.
Inheritance allows a class to inherit properties and methods from a parent class.
Polymorphism allows objects to take on multiple forms and behave differently based on the context.
Encapsulation is the practice of hiding implementation details and exposing only necessary information.
Abstracti...

Prime number code is a program that identifies prime numbers.
A prime number is a positive integer greater than 1 that has no positive integer divisors other than 1 and itself.
The code can be written using a loop to check if a number is divisible by any number other than 1 and itself.
One common method is the Sieve of Eratosthenes, which generates all prime numbers up to a given limit.

Polymorphism is the ability of an object to take on many forms.
Polymorphism allows objects of different classes to be treated as if they are of the same class.
It is achieved through method overloading and method overriding.
Example: A parent class Animal has a method called makeSound(). The child classes Dog and Cat can override this method to make their own unique sounds.
Polymorphism makes code more flexible and r...
