c语言实现数组的倒置的两种方法

/*# include <stdio.h>
int main(void)
{
	int a[7] = { 1, 2, 3, 4, 5, 6, 7 };
	int i, j;
	int t;

	i = 0;
	j = 6;
	while (i < j)
	{
		t = a[i];
		a[i] = a[j];
		a[j] = t;
		i++;
		j--;
	}
	for (i = 0; i < 7; i++)
	{
		printf("%d\n", a[i]);
	}
	return 0;
}*/
# include <stdio.h>
int main(void)

	for (int i = 0; i < 5 ;i++)
	{
		scanf_s("%d", &a[i]);
	}

	
	for (int i = 4; i >= 0; --i)
