Software engineering researchers and practitioners noticed that parts of software projects could often be solved using approaches that were discovered earlier to solve similar problems. This led to the documentation of software design and architectural patterns, which are known solution approaches to a class of problems. 

This course starts by putting software patterns into perspective by answering the question, “What is a software pattern, and how is it different from an algorithm?” You will then learn about the two classes of patterns—software design and architecture patterns. Next, you’ll learn common C++ idioms. Finally, you will learn about software patterns for concurrency. 

By the end of the course, you will have useful and practical tools to improve the quality of your code and productivity. You’ll also be able to analyze a given part of your software project, pick the right pattern for the job, and apply it.

Master Software Design Patterns and Architecture in C++

# Problem statement
You're given a `LegacyRectangle` class, which has an `oldDraw()` method. For the sake of the challenge, you can assume that your client is unable to interact with the `oldDraw()` method directly. Your task is to write the code inside the `RectangleAdapter` that will work as an adapter between the client code and the `LegacyRectangle`'s `oldDraw()` method. 

# Coding challenge
Try to solve this question on your own, but if you're unsure about how to do it, you can refer to this 
#concept=hint#hint#concept#.


Test your understanding of the adapter design pattern by implementing it through delegation.
