UE5 写一段c++ handingmodel的示例

好的，以下是一个简单的C++ HandingModel示例：

#include <iostream>

class HandingModel {
public:
    virtual void move() = 0;
};

class BasicHandingModel : public HandingModel {
public:
    void move() override {
        std::cout << "BasicHandingModel move." << std::endl;
    }
};

class AdvancedHandingModel : public HandingModel {
public:
    void move() override {
        std::cout << "AdvancedHandingModel move." << std::endl;
    }
};

int main() {
    HandingModel* bm = new BasicHandingModel();
    HandingModel* am = new AdvancedHandingModel();

    bm->move();
    am->move();

    delete bm;
    delete am;

    return 0;
}

这里定义了一个抽象类`HandingModel`，它有一个纯虚函数`move()`。然后派生出两个具体的类`BasicHandingModel`和`AdvancedHandingModel`，分别实现了`move()`函数。在`main()`函数中，我们创建了一个`BasicHandingModel`和一个`AdvancedHandingModel`的实例，然后分别调用它们的`move()`函数。最后记得手动释放内存。
