从两边依次交换数组内容

交换数组内容

#include #include #include #include //调用windows自带的函数int main(){    char arr1[] = "welcome to my blog!";    char arr2[] = "###################";    int left = 0;    int right = strlen(arr1) - 1;    //int right = sizeof(arr1)/sizeof(arr1[0])-2;计算数组最后元素的下标    while (left <= right)    {        arr2[left] = arr1[left];        arr2[right] = arr1[right];        printf("%s\n", arr2);        Sleep(1000);//每次输出暂停一秒        system("cls");//清除屏幕中所有显示        left++;        right--;    }    printf("%s\n", arr2);    return 0;}
