在文件中存储2D数组，然后加载C++时出现问题

#include <iostream>
#include <fstream>

const int ROWS = 3;
const int COLS = 3;

void saveArrayToFile(int array[ROWS][COLS], const std::string& filePath) {
    std::ofstream file(filePath);
    if (file.is_open()) {
        for (int i = 0; i < ROWS; i++) {
            for (int j = 0; j < COLS; j++) {
                file << array[i][j] << " ";
            }
            file << std::endl;
        }
        file.close();
        std::cout << "Array saved to file." << std::endl;
    } else {
        std::cout << "Unable to open file." << std::endl;
    }
}

void loadArrayFromFile(int array[ROWS][COLS], const std::string& filePath) {
    std::ifstream file(filePath);
    if (file.is_open()) {
        for (int i = 0; i < ROWS; i++) {
            for (int j = 0; j < COLS; j++) {
                file >> array[i][j];
            }
        }
        file.close();
        std::cout << "Array loaded from file." << std::endl;
    } else {
        std::cout << "Unable to open file." << std::endl;
    }
}

int main() {
    int myArray[ROWS][COLS] = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};
    std::string filePath = "array.txt";

    saveArrayToFile(myArray, filePath);
    loadArrayFromFile(myArray, filePath);

    // 打印加载后的数组
    for (int i = 0; i < ROWS; i++) {
        for (int j = 0; j < COLS; j++) {
            std::cout << myArray[i][j] << " ";
        }
        std::cout << std::endl;
    }

    return 0;
}
