如何在c++中重载<<操作符以打印数组的内容？

#include <iostream>

class Array {
private:
    int* data;
    int size;

public:
    Array(int* arr, int n) {
        size = n;
        data = new int[size];
        for (int i = 0; i < size; i++) {
            data[i] = arr[i];
        }
    }

    friend std::ostream& operator<<(std::ostream& os, const Array& arr) {
        for (int i = 0; i < arr.size; i++) {
            os << arr.data[i] << " ";
        }
        return os;
    }
};

int main() {
    int arr[] = {1, 2, 3, 4, 5};
    Array myArray(arr, 5);
    std::cout << myArray << std::endl;
    return 0;
}

1 2 3 4 5
