交换数组内容

#include <stdio.h>#include <stdlib.h>#include <string.h>#include <windows.h>//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;}

字符串可以改变
