在两个派生类之间执行专用代码

#include <iostream>

class Base {
public:
    virtual void execute() {
        std::cout << "Base class execute" << std::endl;
    }
};

class Derived1 : public Base {
public:
    void execute() override {
        std::cout << "Derived1 class execute" << std::endl;
    }
};

class Derived2 : public Base {
public:
    void execute() override {
        std::cout << "Derived2 class execute" << std::endl;
    }
};

int main() {
    Base* basePtr;

    Derived1 derived1;
    Derived2 derived2;

    basePtr = &derived1;
    basePtr->execute(); // 输出：Derived1 class execute

    basePtr = &derived2;
    basePtr->execute(); // 输出：Derived2 class execute

    return 0;
}
