Summary

In this chapter, we have begun our pursuit to become better C++ programmers by expanding our repertoire beyond OOP concepts to include the utilization of design patterns. Our primary goal is to enable you to solve recurring types of coding problems using tried and true solutions by applying common design patterns.

We have first understood the purpose of design patterns and the advantage of employing them in our code. We have then specifically understood the premise behind the Observer pattern and how it contributes to OOP. Finally, we have taken a look at how we may implement the Observer pattern in C++.

Utilizing common design patterns, such as the Observer pattern, will help you more easily solve recurring types of programming problems in a manner understood by other programmers. A key tenant in OOP is to strive for the reuse of components whenever possible. By utilizing design patterns, you will be contributing to reusable solutions with more sophisticated programming...
