How do I replace inheritance with composition when appropriate?

Learn how to replace inheritance with composition in C++. This approach promotes flexibility and reusability in your code, allowing you to create complex behaviors without the rigid structure of inheritance.

composition, inheritance, C++, object-oriented programming, code reusability, design patterns

// Example of using composition instead of inheritance in C++ class Engine { public: void start() { std::cout << "Engine starting..." << std::endl; } }; class Car { private: Engine engine; // Composition - Car has an Engine public: void startCar() { engine.start(); // Delegating behavior to Engine std::cout << "Car is running!" << std::endl; } }; int main() { Car myCar; myCar.startCar(); // Starts the Car, which uses the Engine return 0; }
