进阶之路——逻辑与思维的重要性

#include <stdio.h>#include <string.h>int main(){char arr1[] = "hellow world !";char arr2[] = "##############";int i = 0;for(i=0 ;i <= strlen(arr1)/2;i ++){arr2[i] = arr1[i];arr2[strlen(arr1)-1-i] = arr1[strlen(arr1)-1-i];printf("%s\n",arr2);}return 0;}

#include <stdio.h>#include <string.h>int main(){char arr1[] = "hellow world !";char arr2[] = "##############";int left = 0;int right = 0;right = strlen(arr1) - 1;while(left <= right){printf("%s\n",arr2);arr2[left] = arr1[left];arr2[right] = arr2[right];left ++;right --;}return 0;}

这两个代码实现的功能是打印一组字符串，并字符逐渐向中间靠拢
