通过此指针调用受保护的基类方法,该指针在派生类(C++)中转换为基类

#include<iostream>

class Base {
protected:
    void protectedMethod() {
        std::cout << "Base::protectedMethod() called"<< std::endl;
    }
};

class Derived : public Base {
public:
    void callProtectedMethod() {
        // 使用 static_cast 将派生类指针转换为基类指针
        Base* basePtr = static_cast<Base*>(this);
        basePtr->protectedMethod();
    }
};

int main() {
    Derived derived;
    derived.callProtectedMethod();
    return 0;
}

Base::protectedMethod() called
