Delegation in Kotlin

Task: Building a Simple Messaging System

Class Delegation: Message Sender

Create a messaging system where different types of messages (e.g., SMS, Email) are sent using a MessageSender interface. You need to implement two classes, SmsSender and EmailSender, that send messages through different channels.

Property Delegation: Message Logger

Enhance your messaging system by adding a logging feature that tracks how many messages have been sent. Use property delegation to keep track of the count.

Expected Outcome:

Class Delegation: You should be able to create a MessageService instance that can send messages via SMS or Email by delegating the task to the respective sender class.

Property Delegation: The MessageService should accurately track and display the number of messages sent using property delegation.
