This principle helps to keep the code scalable and easy to maintain. It means that a class should allow its behavior to be extended without modifying its source code. The OCP states that a class should be open for extension but closed for modification. This principle helps to keep the code maintainable and easy to understand. It means that a class should have only one responsibility or one job to do. The SRP states that a class should have only one reason to change. Below are some of the principles that guide OOP in C++: Principles are guidelines that help to write maintainable and scalable code. This pattern is useful when you want to add behavior to an object at runtime without affecting other instances of the same class.

It provides a flexible alternative to subclassing for extending functionality. The decorator pattern is a structural pattern that attaches additional responsibilities to an object dynamically. This pattern is useful when you want to decouple the objects that produce events from the objects that consume them. When one object changes state, all its dependents are notified and updated automatically. The observer pattern is a behavioral pattern that defines a one-to-many dependency between objects. This pattern is useful when you want to create objects without exposing the logic of object creation to the client code. The factory pattern is a creational pattern that provides an interface for creating objects in a superclass, but allows subclasses to alter the type of objects that will be created. This pattern is useful when you need to ensure that only one instance of a class is created. The singleton pattern ensures that a class has only one instance and provides a global point of access to that instance.

Below are some of the commonly used design patterns in C++: They provide a template for solving a particular problem and can be applied to different situations. In this blog, we will discuss the best practices for OOP in C++ and how to apply them to create scalable and maintainable code.ĭesign patterns are reusable solutions to common programming problems. It involves understanding the design patterns and principles that guide OOP.

However, writing scalable and maintainable code in C++ requires more than just knowing the syntax. C++ is a popular language for OOP due to its powerful features such as classes, inheritance, and polymorphism. Object-oriented programming (OOP) is a programming paradigm that emphasizes the use of objects to represent and manipulate data.
