将数组和矩阵传递给函数作为指针和指向C中的指针

#include<stdio.h>

// 函数原型声明
void print_array(int *arr, int size);
void print_matrix(int *matrix, int rows, int cols);

int main() {
    int arr[] = {1, 2, 3, 4, 5};
    int matrix[][3] = {
        {1, 2, 3},
        {4, 5, 6},
        {7, 8, 9}
    };

    int arr_size = sizeof(arr) / sizeof(arr[0]);
    int matrix_rows = sizeof(matrix) / sizeof(matrix[0]);
    int matrix_cols = sizeof(matrix[0]) / sizeof(matrix[0][0]);

    print_array(arr, arr_size);
    print_matrix(matrix, matrix_rows, matrix_cols);

    return 0;
}

// 打印数组的函数
void print_array(int *arr, int size) {
    for (int i = 0; i< size; i++) {
        printf("%d ", *(arr + i));
    }
    printf("\n");
}

// 打印矩阵的函数
void print_matrix(int *matrix, int rows, int cols) {
    for (int i = 0; i< rows; i++) {
        for (int j = 0; j< cols; j++) {
            printf("%d ", *(matrix + i * cols + j));
        }
        printf("\n");
    }
}
