Answer 1

#include<stdio.h>

int main()
{
	int n, i, k; int a[10];

	printf("输入n:");
	scanf_s("%d", &n); 
	for (i = 0; i<n; i++)
	scanf_s("%d", &a[i]); 
	printf("正序输出\n"); 
	for (i = 0; i < n; i = i + 1)		//不加；
	{
		printf("数组元素a[%d],元素值%d\n", i, a[i]);
	}
	printf("逆序输出\n");
	for (i = n - 1; i >= 0; i = i - 1){
		printf("数组元素a[%d],元素值%d\n", i, a[i]);   //元素值%d\n
	}
	getchar();
	getchar();
	return 0;
