Differentiate between interface and class in C#.

• An interface in C# only contains method signatures, properties, events, or indexers, while a class in C# can contain fields, properties, methods, and events.

• An interface in C# is used for creating objects, while a class in C# is used for defining behaviors.

• An interface in C# can contain fields, properties, methods, and events.

Explain the concept of inheritance in C# with an example.

• Inheritance in C# is the ability of a class to inherit properties and behavior from multiple other classes at the same time.

• Inheritance in C# is the process of creating a new class from an existing class by changing its name.

• Inheritance in C# is when a class can only inherit from an interface, not from another class.

• Inheritance in C# is the mechanism by which one class can inherit properties and behavior from another class. For example, a 'Car' class can inherit from a 'Vehicle' class, inheriting properties like 'color' and behavior like 'drive'.
