我是否可以重载类类型的<<操作符，以在C++中生成文本和二进制文件，同时能够链接<<操作？

#include <iostream>
#include <fstream>

class MyClass {
private:
    int data;
public:
    MyClass(int d) : data(d) {}

    friend std::ostream& operator<<(std::ostream& os, const MyClass& obj) {
        os << "Data: " << obj.data;
        return os;
    }
};

int main() {
    MyClass obj(42);

    // 输出到标准输出流
    std::cout << obj << std::endl;

    // 输出到文件
    std::ofstream file("output.txt");
    file << obj;
    file.close();

    return 0;
}

friend std::ostream& operator<<(std::ostream& os, const MyClass& obj) {
    os << "Data: " << obj.data;
    return os;
}

std::cout << obj1 << " " << obj2 << std::endl;
