L – Liskov Substitution Principle (LSP) | Master CPP Design Patterns 2026
Liskov Substitution Principle (LSP) The Liskov Substitution Principle is one of the SOLID principles of object-oriented programming. It was introduced by Barbara Liskov in 1987 and it states: “Objects of a superclass should be replaceable with objects of its subclasses without affecting the correctness of the program.” What It Really Means: Imagine you’re working with…

Single Responsibility Principle (SRP) | Master CPP Design Patterns 2026
When writing clean and maintainable code, the Single Responsibility Principle (SRP) is one of the most important design principles to follow. It is the first principle in the SOLID design principles, which are a set of five rules that help developers write better object-oriented code. In this article, you’ll learn: What is the Single Responsibility…

D – Dependency Inversion Principle (DIP) | Master CPP Design Patterns 2026
Definition (Simple Terms) Dependency Inversion Principle : “High-level modules should not depend on low-level modules. Both should depend on abstractions. Abstractions should not depend on details. Details should depend on abstractions.” Let’s Break It Down This sounds complex, right? Let’s simplify. Imagine you’re building a robot. The brain of the robot is the high-level module…

I – Interface Segregation Principle (ISP) | Master CPP Design Patterns 2026
The Interface Segregation Principle (ISP) is one of the five SOLID principles of object-oriented programming. It states: “Clients should not be forced to depend on interfaces they do not use.“ In simpler terms, this principle encourages splitting large, unwieldy interfaces into smaller, more specific ones so that classes only need to implement the methods they…

Adapter Design Pattern in C++ | Master CPP Design Patterns 2026
Introduction of Adapter Design Pattern Adapter Design Pattern : When working on large software systems, you may come across situations where two incompatible interfaces need to work together. Instead of modifying existing code (which may be risky or impossible), you can use the Adapter Pattern to make them compatible. The Adapter Pattern acts like a…
