C++逆序打印数组

#include <iostream>
using namespace std;
int main()
{
	int arr[5] = { 1,2,3,4,5 };
	int start = 0; //起始下标
	int end = sizeof(arr) / sizeof(arr[0]) - 1;//结束下标
	while (start < end)
	{
		int temp = arr[start];//中间变量
		arr[start] = arr[end];
		arr[end] = temp;
		start++;
		end--;
	}
	for (int i = 0; i < 5; i++)
	{
		cout << "arr =  " << arr[i] << endl;
	}
	system("pause");
	return 0;
}
