数组的倒置排序

#include <iostream>
using namespace std;
int main() {
	//用户输入数据
	int arr[5];
	for (int i = 0;i < 5;i++) {
		cout << "请输入第" << i + 1 << "个元素:";
		cin >> arr[i];
	}
	cout << "原数组的顺序为：";
	for (int j = 0;j < 5;j++) {
		cout << arr[j] << " ";
	}
	//进行倒置处理
	int temp;
	int start, end;
	start = 0;
	end = sizeof(arr) / sizeof(arr[0]) - 1;
	while (start < end) {
		temp = arr[start];
		arr[start] = arr[end];
		arr[end] = temp;
		start++;
		end--;
	}
	
	//输出倒置后的结果
	cout << "倒置后的顺序为：";
	for (int k = 0;k < 5;k++) {
		cout << arr[k] << " ";
	}
	return 0;
