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++

# Example 
Let's look at the code of the example we discussed in the previous lesson. We have a `MlModel` base class that defines a template method `applyAlgo()`. It has three steps: 
* `readData()` 
* `writeData()` 
* `trainModel()`

The first two are common to any machine learning model and are implemented in the base class itself. The `trainModel()` method can be implemented in different ways, so it is declared abstract in the base class. This does not stop us from defining `applyAlgo()` as a template method.

We also have `LinearRegression` and `Ann` classes that are derived from the `MlModel` class and are meant to implement the corresponding machine learning algorithms. The client can instantiate a derived class using the base class pointer. Calling the `applyAlgo()` method on the object will invoke the corresponding implementation.
