🚀 Advanced OOPs Concepts in C++ 📂 Project Structure This repository demonstrates core Object-Oriented Programming concepts in C++ using real-world examples with clean and meaningful code.
🧠 Concepts Covered
- ✅ Abstraction Real-Life Analogy:
When you order food in a restaurant, you don’t care how it's cooked — you just care that it arrives! This is abstraction: hiding internal details and exposing only functionality.
🔧 Code Example: cpp Copy Edit class Renderer { public: virtual void renderScene() = 0; // Abstract method }; Derived classes like OpenGLRenderer and DirectXRenderer implement their own logic. Main code just calls renderScene() — it doesn’t care how it works internally.
- 🔁 Runtime Polymorphism (with Abstraction) Renderer* render = new OpenGLRenderer();
render->renderScene();
Output depends on the actual object created — even though pointer type is Renderer*.
- 🧱 Encapsulation Real-Life Analogy: Your bank account is protected. You can check the balance or withdraw, but you can’t access internal code.
cpp Copy Edit class DatabaseConnection { string connectionString; bool isConnected;
public: const string& getConnectionString() const; void setConnectionString(const string& connStr); void connect(); }; Data is private
Accessed via public methods
Safe control via validation inside setters.
- 🚗 Inheritance + 🧬 Virtual Inheritance (Diamond Problem Solved) cpp Copy Edit class vehicle { virtual void move(); }; class car : virtual public vehicle {}; class bike : virtual public vehicle {}; class hybrid : public car, public bike {}; virtual inheritance prevents ambiguity.
Overridden move() in hybrid ensures correct method resolution.
- 👤 User Profile Class (Custom Setter Validation) cpp Copy Edit class userprofile { string name; int age;
public: userprofile(const string& n, int a); void setage(int a); // Validates input }; Validates negative input, shows how encapsulation + validation can protect data integrity.
