044.数组-一维数组案例-元素逆置

#include <iostream>
using namespace std;
int main()
{
    //实现数组元素逆置
    //1.创建数组
    int arr[] = { 1,2,3,4,5,6 };
    cout << "逆置前数组" << endl;
    for (size_t i = 0; i < sizeof(arr) / sizeof(arr[0]); i++)
    {
        cout << arr[i] << endl;
    }


    //2.实现逆置
    //记录起始下标位置
    int start = 0;
    //记录介绍下标位置
    int end = (sizeof(arr) / sizeof(arr[0])) - 1;
    while (start < end)
    {
        //实现元素互换
        int temp = arr[start];
        arr[start] = arr[end];
        arr[end] = temp;
        //下标更新
        start++;
        end--;
    }


    //3.打印逆置后的数组
    cout << "逆置后数组" << endl;
    for (size_t i = 0; i < sizeof(arr) / sizeof(arr[0]); i++)
    {
        cout << arr[i] << endl;
    }

    system("pause");
    return 0;
}
