// ExampleComponent.cpp #include "ExampleComponent.h" #includeIn this example, we define an interface `ExampleComponent` with a single pure virtual function `doSomething()`. We then define an implementation of the interface in the `ExampleComponentImpl` class and provide a factory function `createExampleComponent()` to create instances of this implementation. This allows other parts of the program to use the component without having to know the implementation details. This example can be used as part of a larger system with other components, which can be assembled together to form a complete program. The specific package library used to create these components would depend on the requirements of the system and the preferences of the developer.class ExampleComponentImpl : public ExampleComponent { public: void doSomething() override { std::cout << "Component is doing something!" << std::endl; } }; ExampleComponent* createExampleComponent() { return new ExampleComponentImpl(); }
