[指针三]数组作为参数传递

数组名相当于数组的首地址，通过数组名作为参数传递

Demo1:

#include <stdio.h>void fun(int arr[2]){printf("arr[0] = %d,arr[1] = %d",arr[0],arr[1]);}void main(){int arr_1[2] = {1,2};fun(arr_1);printf("\n");return ;}

Demo2:

#include <stdio.h>void fun(int *arr){printf("arr[0] = %d,arr[1] = %d",arr[0],arr[1]);}void main(){int arr_1[2] = {1,2};fun(arr_1);printf("\n");return ;}
