如何将数组传递给其他函数？

#include <stdio.h>

void modifyArray(int* arr, int size) {
    for (int i = 0; i < size; i++) {
        arr[i] *= 2;
    }
}

int main() {
    int arr[] = {1, 2, 3, 4, 5};
    int size = sizeof(arr) / sizeof(arr[0]);
    
    modifyArray(arr, size);
    
    for (int i = 0; i < size; i++) {
        printf("%d ", arr[i]);
    }
    
    return 0;
}

#include <iostream>

void modifyArray(int (&arr)[5]) {
    for (int i = 0; i < 5; i++) {
        arr[i] *= 2;
    }
}

int main() {
    int arr[] = {1, 2, 3, 4, 5};
    
    modifyArray(arr);
    
    for (int i = 0; i < 5; i++) {
        std::cout << arr[i] << " ";
    }
    
    return 0;
}

import java.util.Arrays;

public class Main {
    public static void modifyArray(int[] arr) {
        for (int i = 0; i < arr.length; i++) {
            arr[i] *= 2;
        }
    }

    public static void main(String[] args) {
        int[] arr = {1, 2, 3, 4, 5};

        modifyArray(Arrays.copyOf(arr, arr.length));

        for (int i = 0; i < arr.length; i++) {
            System.out.print(arr[i] + " ");
        }
    }
}
