有没有一种方法可以使用默认的“内置”(宏生成)并只覆盖单个属性？

class Vehicle {
public:
    virtual void start() {
        std::cout << "Vehicle started." << std::endl;
    }
    // ... 其他方法和属性 ...
};

class ElectricCar : public Vehicle {
public:
    void start() override {
        std::cout << "Electric car started silently." << std::endl;
    }
    // 可以添加新的属性和方法，或者不添加任何东西
};

int main() {
    ElectricCar car;
    car.start(); // 输出: Electric car started silently.
    return 0;
}

class Vehicle {
public:
    virtual void start() { // 确保方法是虚函数
        std::cout << "Vehicle started." << std::endl;
    }
};

class ElectricCar : public Vehicle {
public:
    void start() override {
        std::cout << "Electric car started silently." << std::endl;
    }
};
