C sharp - Inheritance in C#

Definition:
Inheritance in C# is a fundamental object-oriented programming concept where a child class (derived class) inherits members (fields, methods, properties, etc.) from a parent class (base class).

 Key Points:

• Promotes code reusability by allowing you to build new classes based on existing ones.

• The derived class automatically gets all non-private members of the base class.

• Use the : symbol to establish inheritance.

Syntax:

class BaseClass {
    // base class members
}

class DerivedClass : BaseClass {
    // additional or overridden members
}

 Benefits of Inheritance:

• Reusability – no need to rewrite common code.

• Extensibility – add new features to existing code easily.

• Polymorphism – enables method overriding for dynamic behavior.

Types of Inheritance Supported in C#:

1. Single Inheritance – one base class and one derived class.

2. Multilevel Inheritance – class inherits from a derived class.

3. Hierarchical Inheritance – multiple classes inherit from one base class.

4. Note: C# does not support multiple inheritance (a class cannot inherit from more than one class), but it can implement multiple interfaces.
