Question

Accepted Answer

Interface is a blueprint of a class that defines a set of methods without implementation. Used for achieving abstraction and multiple inheritance.

Interfaces are used to define a contract that classes must implement, ensuring consistency and flexibility in code.
Interfaces are commonly used in C# to achieve multiple inheritance, as a class can implement multiple interfaces but inherit from only one class.
Pros of interfaces include achieving abstraction, enabling polymorphism, and promoting code reusability.
Cons of interfaces include the need for implementing all methods in the interface, potentially leading to code duplication.
Example: In C#, an interface 'IAnimal' can define methods like 'Eat()' and 'Sleep()', which classes like 'Dog' and 'Cat' can implement.
