在C++中使用'this'是一个好习惯吗？

class Base {
public:
    void printMessage() {
        std::cout << "Hello, this is a base class!" << std::endl;
    }
};

class Derived : public Base {
public:
    void printMessage() {
        std::cout << "Hello, this is a derived class!" << std::endl;
    }
};

int main() {
    Base b;
    Derived d;
    b.printMessage();
    d.printMessage();
}
